If we examine most of the treatises, which have been published 
upon the diseases of children, we shall find the authors to have 
attempted a description of those peculiar to childhood, rather than 
of the common diseases of humanity, as influenced by that age. 
We shall find, in their works, many dissertations upon certain 
symptoms created with morbid entities, or up>n certain lesions, 
which, by their rarity, attract the attention of all observers, but few 
descriptions of the diseases which a daily practice presents. 
Within a few years, however, authors have begun to study the 
affections of children with particular reference to their pathology. 

Numerous observations, and interesting memoirs, have been pub- 
lished in different periodical collections; young physicians have 
taken the subject for their inaugural dissertations. But from so 
vast a field, all has not yet been reaped ; many important truths, 
scattered here and there, have remained lost for want of being 
incorporated with the body of science. A good book upon the dis- 
eases of children is yet to be written. Far from us the idea of pre- 
tending to undertake, at the present day, so great a labour. We 
leave it to hands more skilful and experienced than ours. But 
desirous of walking in the traces of those, who have preceded us, 
and of profiting by the advantages of our situation, we have thought 
to do something useful in studying this important part of pathology. 
We purpose, (if this undertaking be favourably received,) to pub- 
lish a series of monographs upon the different diseases of childhood. 
A part of our material is already collected, but we wish to confirm, 
by new observations, the ideas we at present entertain. 

Among the diseases of this age, those of the chest are, without 
doubt, both the most important, and the most numerous. We 
commence therefore with them. These present researches upon 
pneumonia will form the first part of a series upon the thoracic 

Before entering upon our labour, we ought to say a few words 
upon the method we have prescribed to ourselves in the perform- 
ance of our undertaking, in order that the reader may appreciate 
the degree of confidence to be placed in our assertions. Situated 


hs internes at the hospital for sick children, we have collected a 
great number of facts. We have, particularly in the latter months 
of the year, taken observations upon all the patients admitted into 
the wards for acute diseases. Among these observations there are 
sixty pneumonias, the analysis of which forms the basis of this 
work. We might have operated upon a much greater number of 
facts, but we have preferred to content ourselves with the analysis 
only of those collected after a rigorous and continued examination 
of the chests of children in the normal state. Being then enabled 
to appreciate perfectly the comparative resonance of the different 
parts of the thorax, we can count upon the exactitude of our 
pathological researches. 1 Each particular fact has been collected 
with all possible care ; the autopsies have been made with the 
greatest detail, and the alterations have been minutely described at 
the moment of the examinations. Our observations being col- 
lected, we have decomposed them into their different elements, in 
order to class, into as many distinct tables, the causes, symptoms, 
pathology, &c. ; from each of these tables we have deduced propo- 
sitions, the developement of which forms the base of this work. If 
we have thought ourselves obliged to proceed with rigour, in the 
analysis of our observations, if the numerical method has always 
served us as a guide, we will aver, that we have avoided, as much 
as possible, the filling our pages with figures and observations, 
which would have rendered their reading both irksome and labo- 
rious ; we have rather preferred to postpone, till the end of the 
work, both the numerical tables and the observations, as vouchers 
destined to prove the assertions which we have advanced. 

We have not contented ourselves with giving merely the result 
of our own experience, but have read and meditated upon the 
works of authors, who have preceded us, and we have taken the 
care to indicate the points, where their observations confirm ours, 
as well as where they are at variance. 

We would not terminate this preface, without tendering our 
thanks to our masters, Messrs. Bandelocque and Bouneau, for the 
wise counsels given, and the affectionate goodness always mani- 
fested to us. 

1 The study of the normal state of the child's chest will form the subject 
of a separate monograph. 




No where among- the ancients, (as remarks M. Leger, 1 ) do we 
find a description of the pneumonia of children : they hardly men- 
tion it, and if Stoll, Sydenham, Merten, Rosen, &c, say a few 
words upon it, it is only when supervening in the course of the 
eruptive fevers. 

In 1823 appeared the first monograph, upon the pneumonia of 
children, a faw years after the discovery of auscultation, without 
the aid of which its history could not have heen given with success. 
M. Leger gave to the disease, he was the first to describe, the name 
of latent, a name deserved before his researches, but which it no 
longer merits, since, at present, its diagnosis is among the things 

M. Leger, after a careful examination of the causes, establishes 
the following divisions : 

1. A latent acute pneumonia, with symptoms more or less well 

2. An acute pneumonia, without the usual diagnostic signs, 
without cough, dyspnoea, &c, but on the contrary simulating some 
other affection, not of the chest, or a meningitis. 

3. A chronic pneumonia consecutive to an acute, or primitively 
chronic ; and lastly, a pneumonia after measles. Twenty-eight 
observations terminate this dissertation, being divided into four 
series, after the divisions of the author; the greater part of the 
cases were in children, aged from two to four years. 

This thesis, although very remarkable, leaves many wants to 
be supplied, many assertions to be corrected. The symptoms, 
principally the stethoscopic signs, are indicated rather loosely; 
many are passed over in silence ; the pathological anatomy is very 
incompletely treated ; the divisions are too multiplied, and the ob- 
servations taken with little care. 

After M. Leger, M. Lenerx, 2 in an inaugural dissertation, enti- 
tled, "The pneumonia of children compared with that of old men,"

spoke of the mamellonated hepatisation peculiar to that organ. He 
described the granulations of vesicular pneumonia as like the 
tubercular, and he attributed them to chronic bronchitis. His 
thesis, although voluminous, was not equal to that of M. Leger, 
and, without any greater detail, contained a greater number of 

M. Leger had laid no great stress on a particular form of hepa- 
tisation, as frequent in children, although he mentioned it under the 
name of partial splenisation. Many pathologists sought to repair 
this oversight : thus in 1828, M. Berton 1 drew the attention of 
observers to the lobular form presented by this affection in chil- 
dren. He described its duration, the incertitude of the symptoms, 
insisted strongly upon the frequency of the termination by pulmo- 
nary abcess, and endeavoured to establish the diagnosis, between 
tubercular phthisis and lobular pneumonia. 

M. Burnet published, in the Journal Hebdomadaire, (July, 1833.) 
some researches on this subject, and laid down the following pro- 

1. The non-complication of pleurisy : 

2. The possibility of cure by induration. 

3. Its attacking indifferently all parts of the lung. 

4. The non-termination by suppuration. 

The thirteen observations, appended to this memoir, leave much 
to be desired ; most of them are deficient in detail, the auscultation 
incomplete, and the general symptoms and progress of the disease 
very superficially described. 

One year later, M. de la Berge, 2 in a memoir based upon detailed 
observations, attempted a complete history of lobular pneumonia. 
He divided the disease into two periods — the sthenic, of short, and 
the asthenic, of longer duration. According to him, the treatment 
should be much influenced by these periods. The precision and 
exactitude of the descriptions of the morbid alterations of the lung 
render the pathological anatomy the most valuable part of this 

Of the five observations terminating this memoir, three only are 
examples of simple lobular pneumonia, and, in these three, the dis- 
ease is very limited, (seven or eight points only). Of the two 
others, there is a pneumonia of an entire lobe in the one and a 
pleuritic effusion in the other. 

About this time, Dr. Gerhard published in the American Journal 
of Medical Science, (August and November, 1834,) some quite in- 
teresting remarks upon the pneumonia of children. 

He divides his patients into two classes, those over, and those 
under, six years of age. He proves that, in the first class, pneu- 
monia, taking place in otherwise full health, is not a grave affcc-

lion : in forty of his patients, only one died. He describes with 
care the symptoms, and discusses the influence of treatment. 

In the second part of his memoir, he treats of pneumonia in 
children from two to six years of age, he demonstrates that in these 
the disease is never developed in perfect health ; he insists upon the 
lobular form of the hepatisation and dwells upon the modification 
of the respiratory sound, and, after a careful description of the ana- 
tomical lesions, he finishes with a few words upon treatment. 

His work, fruit of an attentive observation, and based upon an 
analysis of facts, is without contradiction the most valuable yet 
published. The author, nevertheless, treating exclusively of pneu- 
monia when perfectly evident, has neglected its study, when the 
diagnosis, being more obscure, requires, in consequence, all the at- 
tention of the practitioner. Having laboured in the same field of 
observation, we have necessarily arrived at similar results, but we 
have thought ourselves called upon to modify some of his asser- 
tions, as well as to supply some of his deficiences. 

M. Roudin, 1 in some researches upon the complications of mea- 
sles, presented some remarks upon pneumonia. His observations 
are upon ten children from two to seven years of age. and offer 
nothing not contained in preceding publications. But we cannot 
pass in silence a very remarkable omission in this memoir ; the 
author has neglected entirely to notice the existence of any peculi- 
arity in the form of the hepatisation, not even mentioning lobular 

M. Rufz, 2 has given, nearly verbatim, the memoir of Mr. Ger- 
hard, to the composition of which he had assisted, in analysing a 
part of the cases. 

M. Berton, in his treatise upon the diseases of children, has add- 
ed nothing to the ideas already advanced in his inaugural disserta- 

M. Hourmann, 3 in a communication made to the Medical So- 
ciety of Paris, described succinctly the pneumonia of children from 
two to four years of age. He states, from six autopsies, that the 
lobular form is far from being as common, as is usually supposed ; 
he regards bronchial respiration as normal in children, disputes the 
utility of percussion, and terminates with an observation of reco- 
very in a child, of two years, treated by repeated venesection, 
about a pound of blood having been taken. 

Although we are noticing only works upon children from two 
to fifteen years of age, we cannot pass in silence a very interesting 
memoir, upon the pneumonia of infants, occupying one hundred 
and fifty pages in the work, just published by M. Valleix. 4 This is 
the result of an analysis of fifteen observations; an analysis made

wi;h all the rigour of the numerical method. There are only three 
cases of simple pneumonia; in the others, it complicated other 
affections. The disease commenced by febrile agitation, heat, and 
acceleration of the pulse, followed by cough, dyspnoea, subcrepi- 
tous rale, bronchial respiration, and flatness on percussion com- 
mencing at the base of the lung. 

The constitutional symptoms disappeared after a day or two, and 
were entirely wanting in the cases supervening on oedema. 

After death, the hepatisation occupied the two lungs in the great 
majority of the cases. Ordinarily more marked in the right, than 
leftside, more frequently presenting the lobar than the lobular form ; 
the morbid tissue was always very hard and smooth upon incision. 

After attentively reading all these monographs, we see that none 
except that of M. Leger, .presents a complete picture of the pneu- 
monia of children, while some treat only of the lobular pneumonia 
and of that variety revealed only by obscure symptoms ; others in 
examining only the disease, when idiopathic, neglect entirely those 
numerous and important instances where it complicates other 



In the study of the anatomical lesions, authors have not endea- 
voured to establish the connections between the different species 
of the pneumonias of children ; on the contrary, they have given 
us descriptions of each individual species, without attempting their 
union under one and the same head, as they would seem to require. 
We think also, they have too much neglected the examination of 
those alterations of the respiratory apparatus, which complicate 

To present a complete picture of these morbid appearances, we 
shall describe each kind separately, pointing out as far as possible, 
its nature, and thus treal, in as many distinct paragraphs of vesi- 
cular pneumonia or bronchitis, lobular pneumonia, lobar 1 pneu- 
monia, of the state of carnification, and finish with a few words 
upon the disease after it has become chronic. We shall then study 
the alterations of the bronchial tubes, dwelling particularly upon 
vesicular bronchitis and enlargement of the bronchi. 

We shall endeavour, in each of these articles, to establish the 
connections between these divers alterations,-and finish this chap-

the disease, invading the whole or part of a lobe, as in the adult. (P.) 


ter by a succinct account of the concurrent alterations of other 

Vesicular Pneumonia. 

Trie lung, externally, is flaccid and soft, collapsing, more or less, 
in proportion to the extent of disease. Upon incision, it presents a 
number of granulations of the size of a millet seed, of a gray colour 
bordering: upon the yellow. At first sight, these might be mistaken 
for crude miliary tubercles disseminated through the lung, as we 
often see them in children : but a more.careful examination shows 
a great difference, both in their physical qualities and their nature. 

Tubercles form full and solid bodies : the granulations of pneu- 
monia contain a liquid. Thus, upon incision, some tubercles, 
divided by the knife, present their cut surface on a level with that 
of the pulmonary tissue, while others, escaping before its edge, pre- 
serve their globular forms. These latter upon incision present the 
usual appearance of tubercle. The granulations of pneumonia, on 
the contrary, collapse in giving immediate issue to a drop of puri- 
form liquid, and those which have escaped the knife remain whole 
and spherical. 

If these latter be opened with the point of an instrument, there 
escapes the same puriform liquid, and in the centre we discover, 
though often with difficulty, a small depressed point, departing 
from which, we were, in one case, enabled to trace a small canal. 
a few lines in length, with a smooth internal surface, which was 
doubtless a minutebronchial ramification. There is nothing; com- 
mon then to these two alterations, save their form, general disposi- 
tion and colour. 

From this description it appears probable, that the disease is con- 
fined to the extremities of the bronchial tubes, and that a certain 
number of the pulmonary vesicles, becoming inflamed separately, 
are filled with this puriform liquid, and dilated without any in 
flammatory participation of the surrounding cellular tissue. Doubt- 
less, this appearance of the lesion confined to the pulmonary vesi- 
cle Ins originated the name, vesicular pneumonia ; but perhaps 
this appellation is improper, since the inflammation is confined to 
a sing-le element of the pulmonary tissue ; we would therefore pre- 
fer to call the disease, vesicular bronchitis. 

If it happen, that many vesicles, in the vicinity of each other, 
are affected, the connecting tissue may participate in the disease, 
from which results a little mass, sometimes attaining the size of a 
lentil, presenting, on incision, several of the granulations, or seve- 
ral of the depressed points, which appearance, except this modifica- 
tion from the granulations, is the lobular pneumonia to be presently 
descrihed. There in fact exists, in such a case, vesicular bron- 
chitis surrounded by lobular pneumonia. 

In other instances, the pulmonary tissue, surrounding the dilated 


vesicles, is evidently and generally hepatised, and then we have 
vesicular bronchitis surrounded by lobar pneumonia. 

The bronchi, leading to the diseased portion of the lung, are 
sometimes dilated, sometimes healthy ; the former of which condi- 
tions will be fully noticed in a further part of this work. , 

Lobular Pneumonia. 

Lobular pneumonia is an inflammation occupying one or more 
isolated lobules. It has been described under the names, mamel- 
lonated, partial, disseminated. Its frequency and its gravity make 
it deserving of an attentive examination. 

Externally, the lung is usually soft and flaccid, of a grayish rose 
colour, more or less deep, presenting scattered spots of a violet red, 
generally clearly circumscribed, projecting, solid to the touch, and 
not collapsing like the surrounding portions of the lung. These 
spots, usually circular, sometimes elongated, especially from above 
downwards, are chiefly situated at the posterior border of the lung, 
but they are found, also, in all parts; sometimes they are absent, 
and nothing abnormal is visible, but the finger detects the presence 
of nodosities more or less deeply imbedded in the tissue. 

Upon incision, we find the lung marbled, by a rosy gray, and 
a deep violet red colour; the exterior red spots correspond to the 
deep-coloured parts of the interior; and these spots, as well as the 
others below the surface, form nodules of engorgement, presenting 
the characters of ordinary hepatisation, viz. smooth to the knife, 
granulated upon tearing, easily penetrated by the finger, and sink- 
ing in water. But to establish this latter characteristic, it is neces- 
sary to isolate perfectly the diseased portion, and to select espe- 
cially the centre. Upon prrssure, there is little or no crepitation ; 
and there is exuded a sanious liquid, with small bubbles of air, but 
if we be careful to press only the centre, the liquid issues without 
the air, as in common lobar pneumonia. 

We meet with this species of pneumonia at the first, second, and 
third degrees. 

Then, upon incision, we have the pulmonary tissue marbled, of 
a red or rosy gray, the red parts more or less regularly limited, a 
little less resistant than the surrounding tissue, still swimming on 
the surface, with whatever care we rnayisolate them, exuding upon 
pressure a liquid entirely penetrated with air, and still crepitating 
under the finger. This is the first degree,. 

The second we have already described. 

The third presents itself under so insidious a form, as, without 
particular attention, to be easily overlooked at the autopsy. And 
as, during life, the physical signs arc frequently absent, it "is easily 
Conceivable that the disease may be undiscovered, and considerable 
uncertainty be thrown upon I he cause of death. 

Thus, when the points of inflammation are small in size and 
have passed entirely from the second to the third degree, the dis- 


eased tissue becomes grayish, and presents very little difference from 
the surrounding portions. The reader will therefore easily con- 
ceive, that if it requires a careful attention to establish the exist- 
ence of a lobular pneumonia at the second degree, how much more 
is necessary to recognise it when arrived at the third stage, where 
the peculiar colour, the most common of the marks, has disap- 

But if we pay proper attention, we cannot fail of remarking, that 
in the track of the incision certain lobules are projecting, the vesi- 
cles not collapsing as in the surrounding portions, and that pressure 
in these lobules gives issue to a liquid, rather purulent than serous, 
after which we may easily establish the existence of the other cha- 
racteristic signs. 

This description of the three stages of pneumonia, written with 
the preparations before our eyes, and which is very nearly a conipend. 
of the opinions of all the authors upon the subject, does not appear 
to us, however, to give a perfect idea of the pathological anatomy 
and the progress of the disease. We have thought that we have 
observed two forms of the lobular pneumonia, the one perfectly 
circumscribed, which we would call mamellonated, the other not 
so clearly limited, to which we would give the name of partial. In 
giving these names we would not be understood as thinking to 
describe two distinct diseases ; we consider them only as two forms 
of an identical affection, having a common origin, but a different 
progress; finishing by presenting some modifications of the symp- 
toms, and of which the partial is an intervening stage between the 
lobular and the lobar pneumonia. 

The mamellonated pneumonia forms a nodule of inflammation, 
the colour and appearance of which contrasts strongly with the sur- 
rounding tissue. It is a point of pneumonia perfectly limited, 
thrown into the midst of a tissue nearly or quite healthy, and its 
boundaries are clearly defined, even when the surrounding tex- 
tures are engorged. It may even happen, as we have seen m one 
subject presenting about a dozen of these nodules, that the boundary 
is marked by a circle, or rather by a white resistant spherical cap- 
sule, of about an eighth of a line in thickness, and presenting^ 
fibrous aspect. Usually, the line of demarcation, besides the 
change of colour, is indicated by the collapse after an incision ot 
all the surrounding parts. 

The size of these nodules varies from a hemp-seed to a pigeon s 
ecrcr- their border is generally regular, representing a sphere, or 
some analogous figure, and their number varies from one in a lung 
to twenty, thirty, or even more. 

The partial pneumonia, on the contrary, is less well defined than 
the mamellonated ; its circumference is insensibly confounded with 
the surroun ling textures, without any distinct demarcation, either 
bv change of colour or protuberance of the diseased part ; its vo- 
lume often neater than in the mamellonated form, is, however, 
sometimes the same : its form is not always regular, the inflamma- 


tion extends itself in different directions, and is either every where 
advanced to the second degree, or the centre is alone so, while the 
circumference has only attained the first. 

In this latter case it may happen, that a part of one nodule, still 
at the first stage of inflammation, connects itself with several other 
points of pneumonia, and we have the whole or the greater part of 
a lobe inflamed and presenting the characteristics of the first and 
second degree, scattered without any apparent order through its 

Upon these considerations, we establish the two forms of lobular 
pneumonia, one resulting from an inflammation of one or more 
individual lobules, without any tendency to attack those adjacent ; 
while the other is the consequence of an inflammation developed 
in one group of lobules, gradually involving all the surrounding 
ones. In the first case, the inflammation, if we may use the ex- 
pression, is centripetal, concentrating itself in the lobules primitively 
affected. While in the other it is centrifugal, tending to spread 
and attack all around it. 

Hence the explanation, why the mamellonated pneumonia may 
suppurate and form an abcess, while the partial form tends to be- 
come general or lobar. But that these are only modifications of 
the same form of the disease, is proved by an observation which we 
possess, where one side presented the mamellonated pneumonia at 
the stage of suppuration, and the other the partial form tending to 
become general. 

In these two cases, the following is the state in which we find 
the lung affected : 

If the mamellonated pneumonia have passed into the stage of 
suppuration and abscess, an incision presents to us little cavities, 
in form and disposition answering to the lobular hepatization at 
the second degree. Their volume" varies from that of a hemp-seed 
to that of a large pea. These cavities are filled with pus. mingled 
at times with clots of blood ; they communicate sometimes with 
the bronchi, and at the point of entrance of the bronchus into the 
cavity, the mucous membrane cuds abruptly, presenting the ap- 
pearance of a solution of continuity, quite evident to the sight, and 
shown by the formation of strips, if the caliber of the bronchus 
admit of this method of examination. Many of these abcesses 
however, do not communicate with a bronchus, but are surrounded 
by it, in this manner proving that the interior of a bronchus was 
not in these cases the point of departure of the inflammation. 

We insist strongly upon this latter remark, because it is necessary 
to distinguish carefully these abscesses, which are rare, from another 
more frequent lesion, to be hereafter described, the dilatation of the 
bronchial extremities. One character which will aid us in seek- 
ing this distinction, is, that the parietes of the dilated cavitv are 
smooth, polished, and gradually continuous into the bronchial tube 
whilst in the abscess they present quite a different aspect, the bron- 
chus being seen to open abruptly into the cavity. 



If the lobular pneumonia, already become general, have passed 
to the third degree, we observe it as entirely lobar, and an incision 
presents an aspect which all will recognise from the foregoing 
descriptions : those points which were at the first stage will have 
reached the second, while those at the second will have attained 
the third. The texture will be marbled, with a mingled red and 
yellowish gray. 

There is, however, a difference between a lobar pneumonia and 
a partial pneumonia become general, which consists in the different 
disposition in the lung at thedifferent stages of the disease. Thus, 
in common lobar pneumonia, the disease, commencing usually at 
the base of the lung, advances upwards ; and, whilst the base 
passes to the second degree, the parts above are attacked in the 
first, and thus in succession : while in the other case, the disease, 
having commenced in distinct lobules, presents its different stages 
scattered without order through the lung. 

This consideration may serve to determine, in the dead subject, 
if a pneumonia was primitively lobular or lobar; not universally, 
however, as the pneumonia, in becoming general, may have re- 
mained at the second decree, thus imitating perfectly one originally 

But even in this case, as in the preceding, we usually find in the 
same lobe, or in the same or opposite lung, some distinct lobules, 
inflamed in the second degree, constituting the remains of a defined 
lobular pneumonia, cases which have hitherto been regarded as a 
union of the lobar and lobular pneumonias, — added to all which, a 
careful study of the symptoms during the patient's life-time, will 
materially aid the diagnosis of the two lesions before us. 1 

The anatomical proof of the existence of a lobar pneumonia is 
much rarer in children than adults; for, in general, before five 
years of age, idiopathic pneumonia seldom exists, and after that 
age the disease is seldom fatal. 

Nevertheless, in cases of death from some complication, we have 
seen a sufficient number of such autopsies to convince us that the 
lesion is the same at both these periods of life. 

1 It may be well to mention here a form of pneumonia of children pointed 
out by Ml de la Bergs, under the name of the marginal. It often happens 
in reality, that we find hepatisation slight in extent, seated around the base 
or on the anterior border of the lung ; these hepatisations perfectly resemble 
ordinary inflammations in their pathological alterations, and physical cha- 
racters. The circumstance of the seat and slight extent of the disease suf- 
fice to attract attention. Its symptoms are inappreciable, and we may find 
its cause in the feebleness of the child and the want of reaction in the pul- 
monary organs; allowing those parts most distant from the centre of the 
circulation to become engorged. For we are not to think that it is from an 
excess of vitality that the lungs of children inflame— reasoning thus, the 
lungs of old men should have"" the same attributes of superior vital force, 
judging from the frequency of pneumonia ; besides, in children we ought to 
observe it attack with preference the most vigorous and most healthy, 
whereas the reverse is the more general rule. 


To the distinction of some authors, founded upon the smooth 
surface presented by an incision of the inflamed portion, we attach 
no great importance ; since, even when the texture is smooth 
under these circumstances, it is not the less granulated upon 

After this description of the different forms of the acute pneumo- 
nia of children, we pause a moment to remark, that all these lesions 
are only varieties of the same affection, without any special pecu- 
liarity attached to either; since from one to the other there is but 
a step, and since one can easily transform itself into the other. 

In truth, commencing with the capillary bronchitis, of which we 
shall soon speak in detail, we next arrive at the vesicular pneu- 
monia, or rather bronchitis, which is an evident extension of the 
first, and thence to the true lobular pneumonia, the transition state 
being in those cases where the vesicular bronchitis is surrounded 
by a lobular pneumonia. Besides, all the authors upon this latter 
species of pneumonia have endeavoured to establish it as a conse- 
quence of a bronchitis ; for this propagation of inflammation from 
one tissue to another is easily conceivable, and by it alone we might 
explain the development of lobular pneumonia. In reality, the 
final bronchial ramifications, being independent one of the other, 
we easily conceive how the inflammation propagates itself by iso- 
lated lobules; and the whole, therefore, reduces itself to this, that 
childhood, more than any age, is disposed to capillary bronchitis, 
or to the affections consequent upon it; and having before shown 
the passage of the lobular into the lobar pneumonia, we have com- 
pleted the series of the pulmonary inflammations of children. 

Beginning with capillary bronchitis, advancing to vesicular 
bronchitis, to lobular, and finally lobar pneumonia, we find the 
only difference between these diseases to be in the greater or less 
extent of the inflammation. 

We must, however, guard ourselves against too great a general- 
isation of these ideas, involving, as a consequence, the opinion, that 
in the child all the inflammations of the lung commence by the 
capillary bronchitis, and pass successively through all the decrees 
above described; it will be shown atalater period of this worL that 
pathological anatomy, on the one hand, does not furnish the means 
of positively recognising the existence of the bronchitis; while on 
the other, in the greater number of pneumonias, especially the 
lobar, the bronchitis is not of sufficient extent, and the constitu- 
tional symptoms appear too suddenly to allow of the supposition of 
this propagation of the inflammation from one tissue to the other. 

We would only wish then to establish the existence of these va- 
rieties, the small distance which separates them, and the easy trans- 
migration of one to the other. 

To complete, then, the description of our views upon the pneu- 
monia of this age, it only remains to speak of two kinds of altera- 
tion of the texture of the lung, distinct, and yet offering, perhaps' 


some analogy one with the other : we refer to carnification of the 
lung and chronic pneumonia. 


The former of these alterations, though somewhat frequent, 1 has 
never been described by authors, and is merely alluded to in a note 
to the memoir of M. Rufz. The description, given by him, is how- 
ever exact, and agrees perfectly with our observations. 

The lung, in this state is, externally, collapsed, soft, and flaccid, 
instead of full, hard, and resistant as in pneumonia. Its colour is 
violet, marbled by white lines, disposed in losenges or squares, de- 
fining the lobules, without any crepitation upon pressure. 

An incision presents a texture of a red colour, smooth, resisting 
the pressure of the finger, so as to be penetrable with considerable 
difficulty ; exuding upon pressure a serous bloody liquid destitute 
of air. Its appearance very like the close compact fibres of a mus- 
cle has given it its name. 

The .carnification occupies often the circumference of the base of 
one of the lungs, being then marginal, or else some portion of a 
lobe: the middle lobe is the only one we have seen entirely in- 
vaded ; whilst at other times it affects the lobular form, appearing 
in distinct and separate circumscribed masses. 

From this we see that this lesion affects the peculiar seat of each 
species of pneumonia, never, however, involving any considerable 
quantity of lung. It exists besides in subjects presenting at the 
same time the lobar and lobular pneumonias. 

The first idea, presented to the mind by the examination of this 
tissue, is the resemblance to a lung of a foetus which has not yet 
respired; the vesicles of which have not yet dilated, under the 
• thoracic expansion, to admit the air into their interior. Or we 
might think them to have been obliterated by some disease, an in- 
flammation perhaps, the engorgement having disappeared, without 
leaving the vesicles the power of returning to their former state of 

With these views, we might regard the carnification as a sort of 
termination of pneumonia or as that disease in a chronic stage. In 
fact we possess an observation which would justify this idea; it is 
of a child, presenting for a long time the signs of a pneumonia of 
the ri^ht side, and dying finally of the disease invading the left; 
the autopsy showed a considerable carnification of the right lung, 
at those points where the auscultation had previously established 
the existence of a pneumonia. 

Chronic Pneumonia. 
Authors are by no means agreed upon what we ought to under-

stand by the chronic pneumonia of children, and to show how con- 
fused are their ideas upon this subject, it will be sufficient for the 
reader to know, that some consider it very frequent, while others 
regard it as very rare. 

M. de la Berge speaks of the yellowish gray colour as marking 
the change to the chronic state ; but we can regard this only as 
indicative of the third stage of the disease in children, as is admitted 
on all hands in the adult ; and we must have something besides 
colour to characterise the passage to the chronic state. 

We have never met with any lesion which might be regarded as 
chronic pneumonia, unless it be the carnification just described: 
we shall not attempt therefore any description of this affection. 


Tubercles, so common in youth, might naturally be expected to 
present themselves frequently with the pneumonia of children, never- 
theless they are very rare.' Our results agree perfectly with those 
of Gerhard and Rufz, although we would not as yet agree with the 
latter in the conclusion that measles ought not to be considered a 
cause of tubercles : the question merits a separate attention and 
does not form part of our subject. 

We have observed tubercles in fifteen of forty-three autopsies. 
In three cases they existed in other organs besides the lungs, in 
the bronchial or mesenteric glands ; in the other cases their number 
was small : they appeared to select the superior lobe ; and twice 
we found them at the extremity of a dilated bronchus, and twice in 
the centre of a lobular pneumonia. 

Here terminate our remarks upon the pathological anatomy of 
the pneumonia of children ; we shall refer hereafter 2 to the com- 
parative frequency of each of these affections in the different ages ; 
but we have thought it might be useful to connect with the pre- 
ceding descriptions some account of many other alterations, which, 
mingling their symptoms with those of 'the pneumonia, merit for 
that reason a careful examination. 

The Bronchial Tubes. 

We have made the bronchi a subject of particular attention ■ we 
have noted carefully their caliber, the colour, thickening, and'soft- 
ening of their mucous membrane, as well as the liquids contained 
in their cavities. 

Caliber.— Most of the authors have spoken of the dilatation of 
the bronchi, but without insisting sufficiently, we think upon this 
lesion, which must be so frequent, since we have found it in one 

» We would be understood not to speak of those more frequent cases where 
the tubercles being the principal disease are complicated by pneumonia but 
only of those instances where the pneumonia is the primitive lesion '

quarter of the cases terminating fatally. The dilatation of the 
bronchi affects two forms, quite distinct and apparently the result 
of the difference of seat ; the lesion is sometimes in their course, 
and at others in their extremities. 

In the first instance the scissors, instead of entangling themselves 
in the walls of the bronchi, easily follow the smallest branches and 
arrive immediately at the surface of the lung. Upon laying open 
the bronchus in the whole of its length, we see it, from one of the 
first divisions preserving throughout the same diameter, or even 
perhaps insensibly increasing it. In some cases the dilatation, ap- 
pearing suddenly at some point in strong contrast with the volnmn 
of the bronchus from which it springs, continues so throughout the 
whole extent. Sometimes the dilatation appears only in the smaller 
bronchi, which have then but a slight though perceptible increase. 
We have never seen the spindle-shaped form of dilatation in which 
a bronchus dilates and contracts again almost immediately, in a 
manner to simulate a small cavern. 

Only two cases have presented a thickening of the walls of the 
bronchus ; in one of these it was tripled, and might have been re- 
garded as chronic with relation to the concomitant disease. The 
dilatation sometimes has invaded a large part of the lung; in 
other cases we observe it limited to a space not exceeding a small 

In all the cases except one, the dilated bronchi were surrounded 
by diseased tissue, either hepatisation or carnification ; in one 
case we found only a vesicular emphysema without any inflamma- 

If the bronchi be dilated in their extremities, the incision of the 
lung presents a surface strewn with a number of little cavities, 
communicating with each other, and with the bronchi of which 
they appear the continuation. 

The communication of one with the other is made through an 
opening in a simple membranous partition, or by means of a cylin- 
drical canal apparently a dilated bronchus, and which often fur- 
nishes branches themselves involved in the same disease. It may 
happen, however, that these channels of communication are yet in 
the normal state. 

The greater part of these cavities are surrounded by the lung, 
but in some instances existing at the surface they are merely en- 
closed by the pleura, forming externally a small protuberance, and 
collapsing immediately upon puncture, in this manner simulating 
emphysema. These little cavities contain the same liquid as the 
bronchi, their parietes are smooth, thin, and lined by what is evi- 
dently a continuation of the bronchial mucous membrane. 

This is the alteration liable to be mistaken for the little abcesses 
of lobular pneumonia, but we have already pointed out the diag- 
nostic differences between the two. 

We have now to decide if the dilatation of the bronchus be con- 
sequent or precedent to inflammation of the parenchyma. Although 
16— b ril 2 


difficult of decision, it has seemed to us that the dilatation has either 
commenced at the same time with the pneumonia, or been a va- 
loped in its course, as by the physical signs we have never detect :d 
any symptoms anterior to those of the pneumonia. Its formatioi 
is, perhaps, entirely mechanical, from the sojourn of an abundant 
mucous secretion in the bronchial tubes. A supposition streng h- 
ened by the absence of any thickening of the parietes of the bron- 
chial tubes thus affected. 

Colour — Thickening — Softening. 

The alterations of the mucous membrane, as demonstrating their 
inflammatory state, merit a very peculiar attention. 

We are not to think, however, that an inflammation can be as 
easily demonstrated here as in the intestinal mucous membrane. 
The* conditions of the two cases are widely different, for, 1st, th 3 
simple section of the lung covers the mucous membrane with blood, 
so as to require a careful washing, to arrive at proper conclusions 
of the colour; and 2d, the bronchial tubes, becoming thinner and 
more transparent in proportion as they become finer, allow the sub- 
jacent tissue to impose its own colour upon that of their mucous 
. We are driven therefore to a careful examination of the appear- 
ances furnished by the formation of strips ; now these strips 
although easily obtained in bronchi of any size, are no longer so 
when the caliber commences to lessen, even before it has become 
capillary. In this case then, the tenuity of the vessel opposes it- 
self to any elucidation, by this means, of the pathological anatomy. 

Nevertheless we have thought ourselves justified in admitting 
the existence of a capillary bronchitis, whenever we have found a 
redness equally diffused in the mucous membrane in spite of a 
different colouration of the subjacent tissue, and more especially 
when the liquid in these bronchi was abundant. 

We have established, yet but rarely, the softening and redness 
of the mucous membrane by the aid of the formation of strips ; but 
in the great majority of cases these lesions have escaped us, and 
we are compelled to acknowledge that the existence of the capil- 
lary bronchitis can seldom be proved by pathological anatomy. 

Liquids in the Bronchi. 

As yet these have not attracted any particular attention, and 
although we have made them the subject of a particular study, 
our examinations upon this point have been by no means com- 

We find, however, noted in our observations the greater or less 
abundance of these liquids, and the presence or absence of air in 
them; we find it often remarked, also, that the mucus was grayish 
thin, not viscous, puriform, or else the contrary, viscous, whitish' 



purely mucous; and these remarks have assisted us in the explana- 
tion of certain stethoscopic signs. 

But we would have wished to have been able by more detailed 
observations to determine the relations of the different species of 
inflammations, the bronchial dilatation and the abundance of liquid, 
with its consistence, its tenuity, and its mixture with air; we 
would have wished to see if in the same lung the mucus were 
more abundant where inflammation is seen to have existed, than 
where, although the eye after death detects no alteration of the 
tissue, auscultation has indicated the existence of rales during life; 
if there may exist mucus in the bronchi without pneumonia or 
capillary bronchitis, <fcc. To answer these questions, it would be 
necessary to decide if the decubitus of the body upon the back de- 
termine the gravitation of the fluids to that part. All these details, at 
present left incomplete, will be the object of future study. 

We may nevertheless endeavour to determine whether abund- 
ance of mucus be a necessary proof of an inflammation of the 
bronchi. Upon this subject we are of opinion, that a bronchitis 
cannot be admitted unless we have the existence of the mucus; 
that its presence, in any quantity, however great, by no means 
establishes the bronchitis, for we have seen the fluid where it was 
impossible to admit an existence of this latter, — a fact easily con- 
ceivable, considering the great weakness of children, which prevents 
the expectoration of the mucosities. and allows their accumulation 
upon the surfaces normally secreting them. 

Larynx — Trachea —Large Bronchi. 

Inflammation of these organs in connection with pneumonia is 
not frequent. We have twice seen erosions upon the inferior vocal 
chords ; in one there had been measles with hoarseness, in the other 
entire loss of the voice; inflammation of the large bronchi is very 
rare, once only we have satisfied ourselves of its existence, we 
therefore rest assured that if there is a bronchitis existent with the 
pneumonia of children, it is always capillary. 

Vesicular Emphysema. 

To complete the series of the alterations, which we have met 
complicating pneumonia, we must mention vesicular emphysema, 
which we have sometimes observed. 

It presented, usually, the following appearances. Occupying 
especially the summit and the anterior border of the lung, the em- 
physematous portions did not collapse upon the admission of air 
into the chest ; they appeared of more than the ordinary thickness 
of these parts, and extended towards, or even covered the corres- 
ponding portions of, the opposite lung. 

The lobules of the lung were protuberant, and the pulmonary 
vesicles, more distinct than elsewhere, were unequally though 


slightly dilated, being never seen larger than the head of a large 
pin. We have never met with the appendices described by M. 
Louis. The emphysematous portions felt between the fingers did 
not appear thicker than the healthy tissue. The vesicles were per- 
fectly transparent, and collapsed entirely upon puncture. 

This alteration has appeared due, in some cases, to a rachitism ot 
the chest, causing such a deformation as to compress the lung in 
certain parts. We shall develope this idea in another work, of 
which we have in part the materials. 


Authors have said that pleurisy is rare in the child ; if by this they 
mean, that pleurisy does not complicate pneumonia so generally as 
in the adult, they are right ; but they are mistaken if they imagine 
pleurisy to be in itself a rare disease in children ; since it is very 
common to find in the pleura of this age traces of recent or old in- 
flammations. Thus, in forty-three cases, we have found the pleurae 
healthy only ten times. Nineteen times we have met ancient ad- 
hesions more or less extensive, situated especially along the pos- 
terior border of the lung. Sixteen 1 times we have found recent 
adhesions not differing essentially from those in adults. Thus we 
have met with redness, and vivid injection of the pleura, with yel- 
lowish, soft, elastic, and at times tuberculous false membranes, 
with gelatiniform adhesions infiltrated with serosity, or with lemon 
coloured, clear, or flocculent serous effusions, and finally even with 
effusions of a purulent nature. 

Acute pleurisy has been thought especially rare in children from 
two to five years, (Gerhard and Rufz) : but we have observed it in 
a third of the cases at that age. It appears more frequent in females 
than males, and has always coexisted with a lobar pneumonia, or 
with the lobular form become general. 

Bronchial Glands. 

Often healthy, in other cases however, they were increased in 
volume, softened, reddened, or of a paler hue. Sometimes they 
had undergone tubercular degeneration, but in these the existence 
of tubercles was almost constant in the lungs: and even in one case, 
where one lung only contained tubercles, the glands of that side 
were alone affected. 

As to alterations existent in the organs of other functions their 
description does not form a part of our subject, it will be sufficient 
to indicate them, that their complication may be appreciated. 

1 These numbers form a total of forty-five instead of forty-three, two of 
the observations being doubled, from presenting recent, together with old 



Healthy in all our patients, containing from one half to three 
spoonfuls of a lemon coloured serosity ; one subject, who had suc- 
cumbed to hemorrhagic measles, presented ecchymosislunder the 
fold of this membrane investing the heart; and another presented 
an ecchymosis under the serous membrane lining the fibrous invest- 
ment of that organ, the consequence of pressure from a rachitic 
deformation of the chest. 


Always found in a normal state, both in volume and structure. 
It contained often coagula, either black or fibrinous ; colourless 
in the auricles, and sometimes in the right ventricle. In the case 
of hemorrhagic measles, there were no where any coagula. 

The lining membrane was always smooth, polished, and pale. 
The valves, especially of the left side, presented, rather often, a 
somewhat vivid redness, being thus tinged in one quarter of the 
cases, sometimes on the right, sometimes on the left, and at other 
times on both sides indiscriminately. 


Most generally the nervous system was healthy, with the excep- 
tion of a subarachnoid infiltration, somewhat abundant, but neither 
more so, nor more frequent than in the other diseases of children. 

Once there was a general hardening of the substance of the 
brain and spinal marrow ; but there had been an existence of 
paraplegia, and the child showed some symptoms of asphyxia. 

Digestive tube. — Stomach. 

Seldom but slightly affected ; this viscus has presented the fol- 
lowing alterations : — 

Ten times softening of the mucous membrane of the grand cur- 
vature: ought this to be regarded as cadaveric? 

Redness, in different degrees, without softening or thickening, 
to be regarded as a slight congestion, but not inflammation, five 

Once we found thickening, without injection; once ecchymosis; 
once linear redness along the grand curvature, with softening and 
superficial erosions: and, finally, in one case, after the injection of 
a large quantity of Kermes mineral, we found vivid redness in the 
small curvature, existing in large bands, small lines, or little points, 
with ecchymosis, the softening having attacked indifferently the 
red and the pale portions. 

Small Intestine. 
The lesions we have met in this organ are the following:— some 


arborescent vessels or congestions more vivid than in the healthy- 
state ; thrice a white softening of the mucous membrane in a con- 
siderable extent ; nine times redness and softening in the patches 
of Peyer ; once only any ulceration of these patches. Every one is 
aware that the glands of Brunner appear in children generally very 
protuberant under the mucous membrane, dotted, or reticulated 
with black, without any actual morbid affection. We have, how- 
ever, found them sometimes so red, soft, and swollen, as no longer 
to be regarded in the normal state. 

Large Intestine. 

It is here that we find the most frequent complications of pneu- 
monia. But we must remark, that inflammations of this organ, 
together with those of the lungs, are, perhaps, the direases most 
fatal to childhood. 

The alterations may be classed as follows : — 

1. Colitis, with redness, thickening, and softening. 

2. Abnormal dilatation of the follicular orifices. 

3. Colitis, advanced to ulceration, with or without false mem- 
brane. These ulcerations have always appeared seated in the 
follicles, more numerous at the end of the intestine, and never in 
the caecum. 

4. Softening, without notable change of colour, and with a nor- 
mal thickness. 

5. The easy separation of the mucous membrane from the sub- 
jacent tissue, with or without redness. 

6. Ecchymosis. 

To give, in a fevr words, our conclusions, the digestive tube has 
been the organ most frequently complicating by its affections the 
pneumonia — hardly can we count nine cases where it was through- 
out healthy. The greater part of these affections, especially of The 
large intestine, was chronic, consequently antecedent to the pneu- 
monia ; in proof of this, we have the fact that, in the great majo- 
rity, the pneumonia developed itself in patients labouring under 
some anterior malady. The other abdominal organs were either 
healthy, or their slight alterations hardly deserve attention :— we 
may merely remark, however, that in the case of hemorrhao-jc 
measles, the kidneys presented numerous ecchymoscs, with thick- 
ening of the mucous membrane of their pelves. 




The discovery of auscultation, so eminently useful in the thoracic 
affections of adults, ought to render double service in the study of 
these maladies in a younger age. In reality, during the first years 
of life, the lung most often only betrays its diseases by those signs 
which the physical examination reveals: deprived of this precious 
aid to our investigation, we should be exposed every day to mis- 
take, or to overlook the greater part of the diseases of the viscera 
contained in the cavity of the chest: therefore ought we to pay a 
particular attention to the numerous modifications of the respira- 
tory murmur in this class of patients. 

This subject has not yet received all the care it deserves: the 
character of the rales, their seat and frequency, the changes of one 
into another, and, above all, their respective diagnostic values, have 
not yet been pointed out in a sufficiently clear and positive manner. 
Let us see what the analysis of our facts furnishes upon this sub- 
ject, in examining successively the sonorous, sibilant, mucous, 
subcrepitous, and crepitous rales, the bronchial respiration, and the 
natural respiration, when rude or obscure. 

The sonorous and sibilant rales. — Their characters are the 
same as in the adult, and they are, without doubt, the least im- 
portant of all — their duration is usually very short, (two days at the 
most:) they affect indifferently all parts of the chest, but never in- 
volve it in its whole extent. We find them at different epochs, but 
in a third of the cases (especially in the young subjects) before a 
full declaration of the malady. They precede, therefore, the ap- 
pearance of the bronchial respiration, but seldom immediately, for 
usually we hear other rales before this latter manifests itself: in 
the large number of cases they are intermingled with the mucous 
crackles, and the sounds which replace them are very variable. 
They present hardly any diagnostic value, except in patients from 
two to five years, where the pneumonia usually commences with a 
bronchitis, and where the sibilant rale is often the first symptom of 
this latter affection. We deduce from this the practical consequence 
that, in a child of two years, a sonorous or sibilant rale should 
put the physician upon his guard against the ulterior development 
of a pneumonia. 

As to the producing cause, the inconstancy and short duration 
of these tales have never allowed its discovery: we can, however, 
say. that in no case where they have been present, have we been 
able to discover, at the autopsy, in the corresponding part of the 
Innff, any tumefaction of the mucous membrane of the smaller 


The mucous rale.— This rale resembles that in the adult, and 
does not present any varieties from age. Its bubbles, sometimes 
large, under the form of a crackle, sometimes finer, approach, in 
this latter case, the subcrepitous, with which it is easily con- 

The mucous rule is heard usually both in inspiration and 
expiration, in all parts of the chest, always behind, generally on 
both sides, and sometimes in front. It presents itself at all the 
various periods, at the commencement, a (ew days after, or at any 
point in the course of the pneumonia. 

We have remarked nothing constant in the alterations of the 
respiratory murmur preceding or succeeding it: we have seen it, 
however, succeed to a pure respiration rather oftener than to any 
other species. Its duration has, in general, been very short. This 
latter remark is especially true in children from two to five years, 
for in those from five to ten its progress, sometimes irregular, has 
been more constantly uniform, and its duration longer: it has ex- 
isted throughout the whole of the disease, and when once its 
presence has been established, it was rare that we did not find 
it many days in succession in the same place, more or less ex- 
fended. Seven times in thirty it was mingled with a bronchial 
respiration, especially in children from two to five years: once 
even it manifested itself at evening in a point where, on the morrow, 
we found a bronchial respiration. 

From what we have said, the value of this rale appears superior to 
that of either of the other two : its great frequency, its persistence in 
certain cases, and its frequent coexisting with, or preceding a tubal 
respiration, render it a most precious means of diagnosis. It may, 
therefore, sometimes be regarded as the generating rale of bronchial 
respiration, (only, however, in cases from two to five years.) What 
a difference from the mucous rale of adults, which is only indica- 
tive of a simple catarrh ! 

The subcrepitous rale. — What we have said of the last rale will 
apply, in part, to the subcrepitous, since, in a large number of 
cases, the passage of one to the other is very difficult to seize. 
Generally, it was heard in both the times of the respiration ; some- 
times only in the inspiration, especially when accompanying the 
bronchial sound : once only it existed in the expiration alone. Our 
remarks upon this rale refer especially to children from two to 
ten years, for from ten to fifteen we have observed it but five times. 
It existed oftener on both sides than on one alone : in three quar- 
ters of the cases to a greater extent at the base than elsewhere, but 
we have heard it in all parts of the chest. When existent only on 
one side, it was often mingled with a bronchial respiration : in the 
young subjects, from two to five years, in half the cases where 
heard, it appeared in points where the bronchial respiration after- 
wards developed itself; so that it may be regarded as one of its 
generating rales. Observe, to strengthen this remark, that it was 
precisely in those cases where we had ausculted the patients from 


the beginning, that this succession of symptoms was observed; 
which would encourage the idea that its absence, in the other cases, 
was due to our not having ausculted sufficiently early, rather than 
to its non-existence. 

The duration of this rale was variable — short, three or four days 
at the most, when manifesting itself before the bronchial respira- 
tion — much longer when it succeeded it. In a child of three years, 
under these circumstances, it persisted for two whole months. 

Existing sometimes alone, it was more frequently accompanied 
by a bronchial inspiration or expiration: in some cases it was 
heard around the tubal sound, and, as this latter advanced, the 
rale preceded it to attack the adjacent parts. 

In cases where it disappeared, it was replaced by different altera- 
tions of the respiratory sound presenting nothing constant. 

This rale is of great value in the diagnosis. The fact that it so 
often precedes the bronchial respiration, and is heard where the 
other is soon to appear, establishes, it would seem, a very important 
relation of cause to effect. The shortness of its duration, when 
anterior to the tubal sound, is explained by the rapidity with which 
the hepatisation supervenes: while its length, when succeeding to 
this latter, confirms the remark already made, of the tardy resolu- 
tion of pneumonia in younger children. We can then establish 
the principle, that, when in a child of from two to five years, pre- 
senting for some days some slight modifications of the respiratory 
murmur, the sonorous or sibilant rales, for example, we begin to 
detect a subcrepitons rale with equal and numerous bubbles, there is 
strong reason to suspect the immediate invasion of a pneumonia. 

Crepitous rale. — This rale, pathognomonic of the pneumonia of 
adults, does it exist in children? Gerhard and Rufz say never in 
children from two to five years : this appears to us erroneous, for 
we have observed it in nine of our patients: and we are quite sure 
never to have mistaken for it a subcrepitous rale, as we find it 
clearly mentioned in our notes as a crepitous rale, excessively fine^ 
as in the adult. With the exception of three cases, it has always 
been mingled with bronchial respiration : once it appeared on both 
sides behind, and was replaced the next day by a subcrepitous 
rale: another time it occupied the whole of the right back. In this 
case, the child succumbing twelve hours after, we found the lower 
lobe of a violet colour externally, of a deep red on incision, impene- 
trable to the finger, still swimming upon the surface of water, and, 
when pressed, giving issue to a great quantity of blood, with a little 
air. This description corresponds entirely with the inflammatory 
engorgement of Laennec, and, consequently, the lung, in this case, 
was in progress towards hepatisation, the rapidity of the fatal ter- 
mination alone preventing its arrival there. 

In older children, the "crepitous rale is admitted by all patholo- 
gists. We have met it eleven times, always intermingled with a 
bronchial respiration. Its shortness of duration is quite remark- 


able, one or two clays at most, never reappearing in the points 
where it primitively showed itself. 

The value of this rale is very great, as being a predecessor of 
bronchial respiration ; nevertheless, as compared with the subcre- 
pitous, its importance is diminished by its rarity. 

In closing the history of these rales, we would call the reader's 
attention to their duration being shorter, their march less regular, and 
their transformations more numerous in the child than in the adult. 
Our observation confirms, also, the remark of M. Guernard, with 
regard to the facility with which we cause their disappearance, by 
keeping our little patients a short time seated, and their greatest 
distinctness at the moment when the child is raised from his bed. 

Bronchial Respiration. 

Of all the alterations of the respiratory murmur, this deserves the 
most particular attention : it was present in two thirds of our cases, 
and where it is not in our notes, the lesion was either very limited, 
or auscultation had not been practised during the latter days of life. 
A remarkable fact, often established by our cases, is, that frequently 
this modification of the respiration was only heard in the expira- 
tion, while the inspiration continued pure, or accompanied by some 
rale. In these cases, the expiration, prolonged and bronchial, mani- 
fested its peculiar note in the little accompanying cry. We have 
observed this phenomenon more generally in the younger subjects, 
and at two particular stages of the disease, viz. : either before or 
after the appearance of the bronchial respiration, when the disease 
was beginning to limit itself. 

But why is it that the bronchial respiration was thus more fre- 
quently heard in expiration? 

In children from two to five years, lobular pneumonias, of one 
kind or the other, being, without contradiction, the most frequent 
form of the disease, it is natural to suppose that this stethoscopic 
phenomenon or.gmates in this peculiarity. The little nodules, with 
regard to their influence upon the respiratory sound, have the same 
effect as tubercles. Now, since Jackson, 1 we all know a prolonged 
expiration to be a sign of tubercles scattered in the pulmonarv pa- 
renchyma. In children from two to five years, as we have already 
said, the bronchial respiration was, in a certain number of cases, 
preceded by rales of different natures. In the subjects more ad- 
vanced, it was often ushered in by an obscurity of the respiratory 
sound, and m this c ass, more frequently than in the other, it was 
the first symptom established. ' 

In children from two to five years, it has always existed pos- 
teriorly, and most commonly near the vertebral column 

In those from five to fifteen, we have, in the great majority of

our cases, found it behind : four times only anteriorly, of these 
once at the level of the right middle lobe, once at the anterior and 
middle part of the two lungs, and, finally, in the two other cases 
under the clavicles. In the greater part of our patients, we have 
found it for several successive days. 

In children from two to five years, in cases terminating favour- 
ably, the bronchial respiration disappearing, gave place to divers 
modifications of the respiratory sound. In those cases, on the con- 
trary, where death supervened, it persisted until that event, and 
this persistence, when it coexisted with an increase of the general 
symptoms, was considered by us of very grave import ; whereas 
in a child of nine years, in whom the disease was developed in a 
state of perfect health, the bronchial respiration was heard several 
days after the disappearance of the febrile symptoms, and when, to 
all external appearances, the disease no longer existed. 

Although generally easy to hear, we ought to remark, that the 
presence of rales, the difficulty of inducing our little patients to 
cough, added to their repugnance to examination, sometimes mask 
its character. But without regard to the difficulty of its perception, 
can bronchial respiration in children possibly be confounded with 
any other stethoscopic sign 1 We have no doubt of it. In a good 
number of cases, we have seen persons little accustomed to aus- 
cultation, especially of the healthy lung of children, mistake the 
normal puerile respiralion for the bronchial; nevertheless, the dif- 
ference is great, for however puerile it may be, it always gives the 
sensation of air entering a number of vesicles ; besides, it is only 
heard in the inspiration, whereas the bronchial character especially 
manifests itself in the expiration. 

There is, however, a variety of respiration still more difficult to 
distinguish from the bronchial, viz. a rude respiration; and we 
even incline to think that this rudeness is, in some cases, the index 
of a pathological condition differing only in extent from that giving 
rise to the tubal sound; we have observed it only a small number 
of times. More than this it has offered nothing constant, either in 
its duration or in the rales preceding or succeeding it. 

A bronchophony has always accompanied the bronchial respira- 
tion, whenever we have succeeded in eliciting a few words from 
our little patients; in some cases, the resonance of their plaintive 
cry has replaced with advantage the bronchophony which we could 
not establish. 

The respiration is sometimes quite obscure: this character pre- 
cedes immediately the bronchial respiration, or else shows itself 
at different epochs of the disease. The duration of this state was 
generally very short. 

To conclude ;— of all the signs which auscultation gives us, 
the bronchial respiration is the most precious aid; it is the only 
pathognomonic symptom of inflammation of the pulmonary paren- 
chyma, indicating by its extent that of the disease, and by its per- 
sistence the gravity of our prognosis. 



As a diagnostic sign, percussion is of much less value than aus- 
cultation ; it furnishes no results in the simple lobular form of the 
disease ; it is only useful where the hepatisation is become general, 
or from the commencement has taken the lobar form. We find 
dulness on percussion signalised in many of our cases, always in 
proportion, both in extent and degree, to the bronchial respiration, 
generally developed at the same time with, never, however, before 

Percussion, to be useful, should be practised with much care, 
and the observer should be perfectly acquainted with the natural 
resonance of the child's chest. The thorax of the young subject 
being naturally very sonorous, the flatness is seldom any thing 
more than relative. The comparative sonorousness, also, of the 
different parts of the chest is not to be overlooked ; thus, the infe- 
rior dorsal region being naturally the most resonant, percussion 
has never given but a relative degree of dulness. 

There are even cases of greater difficulty, as where a dour, 
hepatisation has gained the same level on the two sides, and 
where in consequence we have no longer any point of comparison, 
M. Hourmann, who allows but little value to percussion, insists 
somewhat upon important results obtained from the application of 
the palm of the hand upon the chest. He thinks that the vibration 
of the walls of the chest, from the cries of the child, always com- 
municates to the hand upon the diseased side a more decided 
vibratory thrill. 



After the separate study of the alterations of the respiratory mur- 
mur, and the pathological anatomy in this disease, we come natu- 
rally to the question of the correspondence between the two. 

To establish a comparison of this nature, we shall follow the 
same steps as in the description of the pathological anatomy, and 
as in the series of pathological changes we have found a chain 
commencing with the capillary bronchitis and ending with the 
lobar pneumonia ; so, also, we are able to establish a gradation of 
symptoms admitting of a perfect parallel. There is the same dif- 
ference between the stethoscopic signs of the capillary bronchitis at 
one end of the chain and those of the lobar pneumonia at the other, 
as there is between the pathological states of the luno- in these 


cases : and as the intermediate lesions are but the union of the two 
extremes in different proportions, so their symptoms are a propor- 
tionate combination of those furnished by the same extremes. 

To illustrate our remark, a bronchitis reveals itself by a mucous 
or subcrepitous rale ; a pneumonia, by a bronchial inspiration or 
expiration ; and the predominance of either of these in a combina- 
tion of the two, is the index of the like predominance of either of 
the affections — inflammation of the mucous membrane or of the 
parenchymatous structure of the lung. 

For these reasons, and to facilitate our discussions, we give a 
name to each of these extremes. Thus we shall speak of the 
capillary bronchitis, the bronchial mucus, and the mucous and 
subcrepitous rales as the bronchial element, whilst the inflamma- 
tion of the parenchyma, with the bronchial respiration, will be the 
parenchymatous element, the predominance of either making the 
excess of its element in the particular affection of the lung. 

This understood, it remains to us to complete the parallel, in 
properly estimating and specifying the degree of combination of 
the two. In this we shall support ourselves wholly by our observa- 
tions, and although, with our point of departure, we might make a 
diagnosis from theory alone, we shall avail ourselves of this latter 
only to facilitate and illustrate our facts. 

We shall first call the attention to the different varieties of pneu- 
monia uncombined, examining afterwards their symptoms when 
j united with, or complicating some other of the alterations which 

I we have described. 

Vesicular Bronchitis or Pneumonia. 

This affection has always occurred to us in connection with some 
other form of pneumonia, or at least a capillary bronchitis; but it 
is easily conceivable that the bronchial element is here the only 
existent one, both as symptom and pathological state. 

Lobular Pneumonia. 

It is impossible to study the characters of this inflammation in 
> r its state of perfect simplicity, as it is never met with without a co- 
il existent bronchitis, or at least an abundant secretion of mucus ; 
' thus, instead of finding a pure hepatisation, we have a combination 
; of our two elements. 

ffl) But. what a variety of circumstances influence the predominance 
a of one or the other? We have, for example, some scattered points 
iil of pneumonia, with an abundant effusion of mucus; here is predo- 
ii minance of the bronchial element. On the other hand, a case pre- 
iffl sents a slight quantity of mucus, with but thickly disseminated 
:l» points of pneumonia ; here the parenchymatous is the most declared : 
e the same difference, if the little nodules be superficial or central, 

I I voluminous or small in size. 


Hence the great irregularity of the simple lobular pneumonia, 
which has not yet become general. 

It is always to be kept in mind, however, that the bronchial 
element is much more universal than the other, and, as it were, 
surrounding it, it is the more easily detected by the ear. Thus, in 
all cases, where the autopsy has shown a lobular pneumonia of the 
whole or part of the lung, we had during life observed in the cor- 
responding mucous or subcrepitous rales, remarkable for their 
persistence, having endured from the commencement of the disease 
until death. In these cases the percussion has furnished us no 
light, for the resonance was nearly always equal to that of the 
opposite side. 

In a small number of our observations we have met with super- 
ficial points of pneumonia in those parts of the lung where auscul- 
tation had delected a drier and finer rale, surrounded by the moist 
rale of a bronchitis, and this we have regarded as the commencing 
development of the parenchymatous element. 

At other times we have heard a prolonged expiration or a very- 
rude inspiration always accompanied by a rale more or less fine, 
and always at points where the autopsy revealed an assemblage of 
a somewhat large number of the little nodules of pneumonia: in 
these cases, in fact, we consider the lobular pneumonia to play the 
part of tubercles in producing the phenomena of the auscultation. 

We have also heard the bronchial sound in the expiration, and 
even both in expiration and inspiration, in cases where the mucous 
rale became less abundant; and these symptoms have disappeared 
upon the bronchi becoming again filled with fluid. 

This occurred in points where the autopsy afterwards demon- 
strated a lobular pneumonia. 

Finally, we are to observe that all the symptoms of the paren- 
chymatous inflammation are more easily appreciated at the summit 
or middle, than at the base of the lung; it is there that we have 
been most sure of our diagnosis, because there the subcrepitous 
rale is less abundant, and at times even absent entirely. From 
these remarks we may deduce. 

1. Lobular pneumonia is more easy of detection superiorly than 
inferiorly, but as if does not affect any particular part of the Irmg, 
when we find it in one portion we may suppose it to exist else- 
where, and the manifestation of the slightest symptom of the paren- 
chymatous element authorises us to admit its more general exten- 
sion, especially if the bronchial element be very welf declared, and 
the natural symptoms lead us to suspect a pneumonia. 

2. A single examination does not suffice for a positive diagnosis, 
but it should be repeated often in the same day, to seize, if there 
be any, the changes from the one element to the other. 

3. Not being able to augment the parenchymatous element, we 
should seek to diminish the bronchial. Thus, in all cases it is use- 
ful to free the child's chest of any mucosities, and in this wc shall 
have the additional advantage of assisting our diagnosis. 


With these precautions, our stethoscopic diagnosis will be cer- 
tain, if not in all, at least in the greater number of cases ; and if we 
will avail ourselves of the other signs to be hereafter detailed, we 
shall seldom be found at fault. 

Simple Lobular Pneumonia becoming general. 

In those cases the two elements, the bronchial and the parenchy- 
matous, are equal, and manifested nearly at the same time, what- 
ever may be the amount of either. 

It is easily conceivable that the pneumonia must have become 
ahead}' - general in a certain extent, for these two symptoms to be 

Thus, a bronchial respiration or expiration, with a mucous or 
subcrepitous rale and dull on percussion, are the peculiar symp- 
toms of this affection ; we have, however, seen one case where the 
bronchial respiration was not heard till the evening before death, 
although the pneumonia had become general, and advanced even 
to the third stage in some places. In this case, the mucous rale 
was extremely full and abundant, and the bronchial tubes were 
crowded with mucus. # 

When we can follow the march of a lobular pneumonia in 
progress towards the lobar form, we find first the rales, then an 
expiration, or a bronchial respiration, unequally disseminated and 
extending little by little till it involves a considerable space. 

And to chow that this is not merely in the imagination we will 
transcribe a portion of one of our observations. 

1st day. — Right back, subcrepitous rale rather rare in both times 
of the respiration ; at the left summit a little sonorous rale. 

2d day. — Abundant subcrepitous rale on both backs. 

3d day. — Behind, at the left base, and at the middle of the right 
lung, bronchial expiration, mingled with a somewhat coarse sub- 
crepitous rale, heard above and below the point of the bronchial 

4th day. — In the whole height of the right back, bronchial expi- 
ration, with a little subcrepitous rale at the base; on the left the 
bronchial respiration is scattered here and there. 

5th day. — Respiration fully declared as bronchial in the two 
upper thirds of both backs; below, fine subcrepitous rale. 

At the autopsy there was found a pneumonia originally lobular, 
but already become general. 

It remains now to decide if auscultation can teach us the time 
necessary for a lobular pneumonia to become general. Our ob- 
servations offer us little assistance upon this subject ; nevertheless, 
considering the rapidity with which the bronchial respiration de- 
clared itself after the catarrhal period in the case just detailed, we 
may conclude, that its march, once commenced, is very rapid. We 
shall see hereafter, however, that the rapidity of this progress is 


subordinate to the nature of the disease upon which the pneumonia 

Lobar Pneumonia. 

The crepitous or subcrepitous rales, bronchial respiration, bron- 
chophony, and dulness upon percussion are the characters of this 
pneumonia as well in the child as in the adult. 

In the younger children, however, the bronchial element always 
exists : thus in those cases, the rale is more moist than in older 
subjects, where the parenchymatous element, on the contrary, 
predominates in the auscultation as at the autopsy. 

It is only in the lobar pneumonia that we have a difference thus 
made by the age of the patient ; in the lobular form we have been 
able to establish no such distinction. 


This affection is generally of too little extent to give rise to any 
well marked symptom. Most generally we have only noticed a 
mucous or subcrepitoys rale, with a slight diminution of the reso- 
nance upon percussion ; and a careful examination of all our ob- 
servations leaves us with the general idea that in an equal extent 
of lesion, carnification offers much less an amount of stethoscopic 
signs than hepatisation. Twice, however, in a vast carnification, 
we found, in ausculting at various intervals, the bronchial respi- 

Thus far we have the history of the simple cases. But a com- 
plication of the pneumonia with any other disease of the lung must 
cause many modifications in their signs. These complications are 
of two kinds : either several species of simple pneumonia are united 
in the same point, or else there is joined to it some one of those 
lesions, of which we have not yet detailed the symptoms. 

The first division will detain us but a few moments; its signs 
must depend upon the mixture, more or less considerable, of the 
two elements ; we have seen cases of the union of both species of 
bronchitis, the capillary and the vesicular, of this latter or perhaps 
of both with a lobar pneumonia or carnification. In the first case 
the bronchial element existed alone; in the second the parenchy- 
matous predominated. We would be understood, however to allow 
that auscultation does not furnish a differential diagnosis' between 
these simple and the complicated affections. 

The second class comprehends those cases where a dilatation of 
the bronchi, or an emphysema occurs in conjunction with the 

A priori we should be unable to say what might be the influ- 
ence of the dilatation of the bronchi upon the auscultation • for if 
on the one hand it would produce bronchial respiration by the in- 
creased size of the tubes, on the other it must facilitate the mucus 



rale, rendered more abundant and more moist by the quantity of 
tluid, and the greater space allowed to the formation of the bubbles. 
Facts show us that both these circumstances may occur ; we 
have observations of dilatation of the bronchi in which the bron- 
chial element predominates, while in others it is the parenchy- 

But in this latter case we would suggest the question whether 
the mucus was or was not charged with air, for this appears to 
coincide with a remarkable change in the production of the rales. 
We judge so by two cases, in both of which the parenchymatous 
element predominated in the auscultation, whilst at the autopsy 
the bronchial appeared the more abundant : one was a case of vesi- 
cular bronchitis, with a lobar pneumonia, and a very abundant 
quantity of mucus ; the other a lobular pneumonia become general 
in the first and second degree with a dilatation of the bronchi, and. 
also a large secretion of mucus. In the first case, we had a bron- 
chial respiration with very little subcrepitous rale in the same 
points: in the second we had a pure crepitous rale: but in both 
these observations, the mucus was not charged with air, or rather 
we found a puriform liquid, which seemed never to have been 
penetrated by the air, and therefore not to have contributed to the 
stethoscopic sound of bursting bubbles. Thus in these cases the 
sounds emanated from the parenchyma of the lung. 

To conclude, we find only one case of vesicular emphysem 
complicating the pneumonia ; this case, one of the most compli- 
cated of all, was a capillary and vesicular bronchitis, with lobular 
pneumonia at the third stage, dilatation of the smaller bronchi, and 
emphysema, showing the bronchial element in excess as patholo- 
gical alteration and consequently as symptom. Besides the fun- 
damental symptoms, we are to regard also a third — the intensity of 
the respiratory sound. In one case, this, in consequence of the 
emphysema, was nearly nothing, while the resonance on percus- 
sion was exaggerated. In addition, we had presented to us another 
phenomenonwhich, according to Laennec, may be referred to the 
emphysema as cause : thus, at any moment of the disappearance 
of the mucous rale, we heard a succession of dry crackles, a sort of 
gross crepitous rale. These crackles could not be attributed to the 
lobular pneumonia, as they were too large and heard in an extent 
too considerable. 

In this case the emphysema was the phenomenon clearest cha- 
racterised, and its symptoms were the following: 

Mucous rale disappearing after cough, leaving the respiration 
very obscure, with a return of the rale, alternating with the dry 
crackling. Resonance on percussion much exaggerated. 

In conclusion, the following may be regarded as the stethoscopic 
signs of each of the alterations which we have described : 

^Capillary and vesicular bronchitis :— mucous or subcrepitous 
rales; natural resonance upon percussion; lobular pneumonia: 
mucous or subcrepitous rales, mingled at times with a rale more 
16— c ril 3 


dry in its character; a roughness of the respiration ; prolonged or 
bronchial expiration ; resonance natural. 

This latter species become general : — mucous or subcrepitous 
rale, with bronchial respiration scattered or rapidly spreading ; dul- 

Lobar pneumonia; crepitous or subcrepitous rales, bronchial 
respiration, bronchophony, dulness. 

If a dilatation of the bronchi be joined to one or the other of 
these affections, it is sometimes the mucous or subcrepitous rale, 
sometimes the bronchial respiration which are exaggerated. 

In all that precedes we have as yet said nothing of the stetho- 
scopic signs marking the change of the pneumonia from the first 
to the second or from the second to the third degree. We have 
however spoken of one case where a well manifested pulmonary 
engorgement gave for symptom a pure crepitous rale. As for the 
distinction between the second and third degree, it would appear 
impossible to establish it, and for this very simple reason, that 
in all our cases of gray hepatisation, there existed no considerable 
softening of the parenchyma. Now Laennec asserts that the infil- 
tration of pus into the pulmonary parenchyma affords us no new 
sign, as long as it remains in a concrete state. But even supposing 
the pus to have softened, the mucous rale, which, according to this 
author, indicates the change, would be of no use to us. considering 
its excessive frequency in children. 



After the study of the anatomical lesions in the pneumonia of 
children, and the exposition of the physical symptoms which cor- 
respond to them, we come naturally to the question of the circum- 
stances favouring the development of the disease under considera- 

A fact, which strikes at first view, and which has been noted by 
ail authors, is, that in the large majority the pneumonia supervenes 
in the course of some prior affection. This has been especially 
insisted upon in children of from two to five years. Gerhard and 
llufz go even so far as to say that idiopathic pneumonia does not 
exist at that age. This assertion we cannot admit in all its rigour, 
since we possess three examples of children of five years, in whom 
the disease was developed in the midst of perfect health : but we 
recognise the truth of the general proposition ; of forty patients be- 
tween these ages, only three were in full health at the commenee- 
ment of the pneumonia. 

But more, it is not solely in these first years of life that the dis- 

CAUSES. , 35 

ease is rare in an idiopathic form : it is the same in the succeeding 
periods. Our observations prove this very evidently. Of twenty 
patients from six to fifteen years, six only were in good health at 
the invasion of the malady, the others were attacked with different 
diicases: measles, small-pox, typhoid fever, hooping-cough, gan- 
grene of the mouth, &c. 

From these remarks it results that children may be attacked with 
two kinds of pneumonia; one somewhat rare which may be styled 
the idiopathic, or the primitive, the other much more frequent, 
which we shall call the complicated or secondary form. 

This fact once admitted, what are the causes exerting an influ- 
ence upon the development of this inflammation. 

Age is one of the most efficient of the predisposing causes, since 
from two to five years the malady is by far the most frequent. In 
sixty patients, forty were from two to five years of age, and twenty 
between five and fifteen : and the real proportion is even greater 
than this, as the number of beds in the ward for the older children 
is much the more numerous, and the admissions there consequently 
more frequent. 

To corroborate our assertion we will cite the result of the tables 
of pathological anatomy drawn up by M. Haese, who in one hun- 
dred and eight autopsies found a pneumonia seventy-one times in 
children between two and five years, and thirty-seven times Only 
between the ages of six and fifteen. 

Age exerts an influence not merely upon the frequency of the 
disease, but equally upon its particular form. We are of opinion, 
however, that the proposition, that lobular pneumonia is peculiar 
to the younger class of children, is too general — for although with- 
out any doubt it is more frequent at these ages,' still we possess an 
observation of a perfectly well marked lobular pneumonia in the 
partial form, in a child of nine years. And. in an examination of 
facts furnished by our predecessors, we find, that the first case of 
M. Burnet, is this form of the disease succeeding to measles, in a 
girl aged eight years ; and his fifth is of the same affection in a 
child of nine and a half years : and lastly M. de la Berge's first ob- 
servation is in the same category. 

Another fact, tending to limit the influence of early age upon the 
particular form of the disease, is, that from the observations of MM. 
Valleix and Vernois, the lobular form is very rare in infants. 

Sex has not appeared to us to exercise any well marked influ- 
ence upon the development of the pneumonia in the first class of 
our patients ; neither has it in the second series, when the disease 
complicates some pre-existing affection : but according to Ger- 
hard, idiopathic pneumonia from the ages of five to sixteen is more 
common in males than females. 

Authors vary upon the time of the year most favourable to the 
production of pulmonary inflammations. M. de la Berge, reason- 

1 See table of Pathological Anatomy. 


ing from the fact of the great number of eruptive fevers in spring 
and autumn, advances an opinion that lobular pneumonia is more 
frequent at these seasons. M. Leger makes the same observation ; 
and Dr. Gerhard assures us that idiopathic pneumonia is the most 
common in the months of April and May. 

One of our colleagues, M. Becquerel, having had the kindness to 
place at our disposition a list of the pneumonias occurring in the 
service of acute diseases, (girls.) during the months of April, May, 
and June, we are enabled, in uniting his notes with ours, col- 
lected at the beginning and end of the year, to give a complete 
table of all the pneumonias observed in this service during the year 
1837. We would observe, however, that circu mstances beyond our 
control having prevented the observation of a few cases, which 
occurred in the latter end of March, this month will not enter into 
our table of results. The total of pneumonias in the eleven months 
is ninety-four, divided as follows: 

(We have marked not only the number of the pneumonias, but 
also the relative frequency of the idiopathic and complicated.) 




























Total, 94 13 81 

Different consequences may be deduced from the foregoing 
tables. 1. What we already knew ;— the enormous disproportion 
between the frequency of the idiopathic and complicated pneu- 
monia; 2. the rarity of idiopathic pneumonia in the warmer 
months of the year. We may moreover observe, that the number 
of complicated pneumonias depends upon the prevalence, at the 
time, of those diseases, upon which they are liable to supervene. 
Thus if the month of February presents the largest number, we 
find the cause in the epidemic prevalence of the grippe at that sea- 
son of this particular year, (1837.) 

Taking into account the force of the constitution, we have made 
the remark that nearly all our younger class of patients presented 
a very delicate complexion, while those from six to fifteen years 
appeared generally to enjoy a very good constitution. 



Different debilitating causes appear to exert a very manifest in- 
fluence upon the pneumonia of children, we refer particularly to 
the diseases in the course of which the affection of the lungs su- 
pervenes, a prolonged residence at the hospital and the continued 
decubitus upon the back. 

It will not be uninteresting, to examine what are the affections 
with which the pneumonia is most frequently complicated, as well 
as the comparative frequency of these diseases in the different ages 
— a glance at the following table will satisfy us upon these points : 

From tioo to five years. 


Measles, .....

Varioloid, or scarlet fever,

From this table it results, that from two to five years of age 
measles is the disease most frequently complicated by pneumonia, 
then chronic enteritis and hooping-cough ; whilst after five years 
it is measles, with small-pox second in frequency. Although in 
our result gangrene of the mouth only appears three times, we 
can assure the reader, that, of all the diseases of children, it is the 
most frequently complicated by pneumonia; for we have seen this 
inflammation in eleven cases of gangrene of the mouth ; and M. 
Baudelocque's experience is perfectly in accordance with our own. 

Independently of the diseases just mentioned, predisposing more 
or less decidedly to pneumonia, we would observe that the cuta-

these tables, as we have eliminated all the cases of pneumonia supervening 
in advanced phthisis. 


neons system presented different affections (ecchymosis, eczemas, 
&c.) in one half of our cases. 

The prolonged sojourn at the hospital, and especially the decubi- 
tus upon the back, have been very justly considered by M. Leger. as 
prejudicial to young children ; an assertion confirmed by our own 
cases, for we possess observations in which the sole cause, which 
could be considered as productive of the disease, was the long de- 
cubitus upon the back. 

The explanation of this is easy. The weakness and the diffi- 
culty of the expectoration in children, favours, in certain cases, the 
stasis of the liquids in the most inferior portions of the lung, where 
their sojourn determines an inflammation of the neighbouring 
parts, — we say determines the inflammation, because, in the great 
number of cases the anatomical changes have not appeared to us 
as analogous to those of the hypostatic pneumonia, and we would 
not give a purely mechanical explanation either of the lobular or 
lobar hepatisation. We advance here an opinion directly opposed 
to that of Dr. Gerhard, who thinks that pneumonia in children 
from two to five years of age possesses a very great analogy with 
those sanguineous congestions resulting from a mechanical obstacle 
to the free circulation of the blood in the lungs. It seems to us, that 
to refuse to the pneumonia of young children any purely inflamma- 
tory character, is to put ourselves in direct opposition to facts. A 
rapid progress, formidable symptoms of reaction, evident traces of 
an inflammation in the lung or its dependances — are not these suf- 
ficient to characterise an inflammatory affection ? 

Authors have not contented themselves with the simple causes 
above enumerated, but have wished to ascend higher, and seek in 
the peculiar structure of the child's lung, the rapidity of the circu- 
lation, the number of inspiratory movements, &c, an explanation 
of the frequency of pneumonia at this age. So far these pretended 
causes are to be considered merely as flights of fancy, more or less 
ingenious, not as settled and positive facts. 

Latterly MM. Burnet and De la Berge have sought to connect 
pneumonia with a cause more general than any we have men- 
tioned. They have advanced that the lobular pneumonia always 
succeeds to an inflammation of the bronchial tubes. This is a 
question of sufficient importance to receive a special and attentive 

If our details, when upon the subject of the pathological anato- 
my, be recalled, it will be seen that in many cases the most atten- 
tive examination of the smaller bronchi did not enable us to assure 
ourselves of the existence of an inflammatory lesion of these tubes. 
Pathological anatomy thus affording no light, we are obliged 
to have recourse, for a solution, to a careful examination of ^he 
symptoms. And what do these teach us? That in the great ma- 
jority of cases, not only in the variety described by M. dela Berge, 
but also in the diffused lobular species, and even in the lobar form 
in the youngest children, there exist cough and different altera- 



tions of the respiratory murmur, supposed to be dependent upon a 
bronchitis, before the positive signs of a parenchymatous inflamma- 
tion have declared themselves. 

Therefore, without denying the possibility of a pneumonia origi- 
nally commencing in the parenchyma, in children from two to five 
years (for we possess examples of it) we regard the occurrence as 
exceedingly rare. But very frequently it is impossible to recognise 
any connection between the gravity or extent of the catarrh which 
precedes, and the pneumonia which follows; so that the bronchitis 
ought to be regarded as predisposing to inflammation of the paren- 
chyma, rather than as an occasional active cause ; and the pheno- 
mena to be those of a propagation of inflammation in continuous 

Thus, to sum up ; — nearly all the causes of pneumonia in children 
are reduced to the predisposing; and if a change of temperature, a 
suppression of an habitual discharge, a repercussion of a cutaneous 
disease, or the exanthemas, are capable of its production, our ob- 
servations enlighten us very little with regard to the degree of their 
influence. We have, however, thought ourselves to have observed 
that sudden changes of temperature had a manifest influence upon 
the development of this disease. Thus, in two cases, we have 
imagined that a sudden chill appeared to have been the occasional 
cause of the appearance of the pneumonia. In one of these a 
young girl, ill with measles, was seized with all the symptoms of a 
pneumonia (cough, pleuritic pain, &c.) after putting her feet upon 
the ground, the eruption being in full vigour; in another, a young 
boy, going out the eighth day of the eruption of small-pox, was 
taken'' four days after with cough, dyspnosa, and we discovered from 
the day of entrance all the signs of a pneumonia at the second 
degree. We have observed, in young children labouring under 
diseases of the skin or hairy scalp, the falling off of the scabs or 
the suppression of the discharge, far from being the cause, to be 
rather the result of the inflammation, and the affection of the skin 
to be sensibly modified after the full development of the pneu- 



The pneumonia, once declared, determines in the organism an 
assemblage of symptoms which we must attempt to comprehend. 
It has been lately often repeated, 1 that children manifest in their

at the Enfans Malades, upon the lines of the countenance as diagnostic of 
visceral disease. — P. 


countenances, the signs of the diseases with which they are attacked; 
it has been admitted that certain modifications of the lines of the 
countenance correspond constantly with certain thoracic or abdo- 
minal affections: we have attempted, in the larger part of our 
cases, to appreciate the value of these diagnostic signs, and the fol- 
lowing are our results : — 

We have remarked nothing constant in the different folds of the 
skin of the countenance ; they appeared to us rather as the index 
of a general suffering than as pathognomonic of disease of the 
viscera, either of the chest or abdomen. We will not say the 
same, however, of the dilatation of the alas nasi, which we have 
observed in nearly all our cases, immediately preceding the inspira- 
tion, and lasting nearly the whole period of the disease. Sometimes 
it was excessive, and nearly always proportionate to the acuteness 
and gravity of the pneumonia. In young children the general 
expression of the countenance was very various — sometimes pale, 
sometimes coloured, at times only on a single cheek, but without 
any reference to the side affected by the pneumonia; it offered in 
several cases, from the commencement of the disease, a profound 
and characteristic alteration, followed by a rapid emaciation. But 
it would be wrong to consider this facial alteration as peculiar to 
the younger series, for we find it noted in several of our observa- 
tions of children from six to fifteen years, in whom the termination 
of the disease proved fatal. 

Paleness and puffiness of face are notes in many of our observa- 
tions, coinciding often with infiltration of the extremities. 

In young children, being unable to establish the existence of a 
chill, we cannot say if the disease commences in this manner ; but 
we are certain that, after the invasion of the pneumonia, the heat 
of the skin was sensibly exalted in the larger part of our patients: 
most usually it was great, sometimes excessive, but almost never 
accompanied with moisture. 

In older children the disease commences with a very apprecia- 
ble chill, to which the heat of the skin soon succeeds. 

The pulse was always counted— rarely under 120* in the 
younger children it varied between this number and 140 to 150, 
and has been observed as high as ISO. In children from six to 
fifteen years it was less accelerated, as it more rarely attained 140 
to loU, but the day of invasion it was always 120 

In the greater number of cases after the commencement it pre- 
sented no special character: usually full and regular, but nearly 
always in the younger children, a few days before death, it became 
ot an extreme smallness, sometimes nearly imperceptible. In the 
cases terminating favourably, this smallness of the pulse was never 
observed at any period of the disease. 

The number of inspirations varied between thirty and eighty, in 
DetwepiZ T tW ° S° fiVe ^ rS; in th0se from six ^fifteen, 

n en H ? ^ r and T y - e] °- h{ - lD the half of lhe cas es the; 
presented nothing particular; in the other half, at all ages but 



specially in the younger series, we observed the following pecu- 
liarities:— Sometimes they were anxious, very full, raising the 
whole chest, or else they were entirely abdominal ; at other times 
they were irregular, unequal, and interrupted; in some cases the 
inspiration was normal, the expiration alone being hard, noisy, 
painful, difficult at the commencement, and seeming to exact an 
effort, and to be rather an active than a passive phenomenon. 

A great number of our cases of pneumonia declaring themselves 
at the hospital, we have been able to establish the increase in the 
number of inspirations and pulsations at the moment of the decla- 
ration of the disease ; we cannot too much insist upon the simulta- 
neous appearance of these two symptoms. But we would be care- 
ful to say that it is only on the first, second, or third day that we 
are able to remark this, since later in the disease, under the influ- 
ence of treatment, or causes which escape our observation, the 
comparative march of the pulse and respiration becomes often irre- 
gular, and even inverse: that is to say, we find an increase in the 
number of pulsations to correspond to a diminution of the number 
of inspirations, and vice versa. 

After this separate examination of the pulse and respiration, let 
us see the influence of the extent of the hepatisation upon these two 
symptoms. When there was no complication of other acute dis- 
ease, the acceleration of the pulse and respiration has been in direct 
proportion to the acuteness and extent of the inflammation, with 
the exception of some cases already alluded to, where the discre- 
pancy was to be attributed in part to the treatment. 

In the cases of pneumonia co-existing with an acute disease, the 
measles, for example, the acceleration of the pulse and respiration 
was sometimes extreme, although the inflammation of the lung 
was very limited. 

We think, therefore, that we may sny, in general the intensity of 
the febrile reaction depended upon the extent of the inflammation. 
This result, although a rigorous deduction from facts, so simple as 
to appear to be established a priori, is nevertheless opposed to what 
has been written by authors upon the lobular pneumonia; who 
state the pulse and respiration to be always much accelerated. 

An examination, however, of these observations of MM. Burnet 
and de la Berge, shows us, that in all the instances of acceleration 
of the pulse and respiration, the fever explains itself very naturally 
by the existence of certain coexisting affections, measles, typhoid 
fever <fcc. Independently of the extent of the hepatisation, the 
reaction depends on the nature of the disease upon which the pneu- 
monia supervenes ; we shall have occasion to revert hereafter to 
this latter consideration. 

When an effusion into the cavity of the pleura complicated the 
pneumonia, we find mentioned in our notes a collection of symp- 
toms which in a similar case might serve for diagnosis. We refer to 
the paroxysms of suffocation. The oppression becomes extreme the 
inspirations succeed each other with a prodigious rapidity, the face 


is purpled, and these symptoms all disappear, to he in a short time 
reproduced. In ordinary pneumonia the difficulty of the respira- 
tion is sometimes very great; but in general its progress is more 
or less regular, whether in the increase or decline, and does not 
show itself thus under a paroxysmal form. 

In cases where the respiration has been irregular or unequal, we 
have not observed these circumstances to be dependent upon any 
greater or less intensity of the inflammation ; in two cases, one of a 
pneumonia of the whole posterior part of the lung, comprising also 
the whole superior lobe, and the other only of the summit, the 
respiration was in both remarkably unequal. And finally, in those 
where it is noted as anxious, raising the whole chest, the pneumo- 
nia was very extended, occupying even nearly the two entire 

The cough has been wanting twice: another time it was exces- 
sively rare, (lobular pneumonia.) In regard to the great number 
of cases in which it existed, it ought to be ranked among the im- 
portant symptoms : but its value as such is much affected, inso- 
much as it often occurred before the other signs of pneumonia 
could be found to exist. In more than one half of the cases it is 
noted as rare; but in those where it was observed as frequent, it 
increased quite sensibly in proportion to the progress, and in direct 
ratio with the extent of the inflammation. It diminished, however, 
with the strength of the patients, and in the last days of life it was 
entirely wanting. Nearly always it was dry, and in eight cases it 
existed in paroxysms ; but in five of these there was a complication 
of hooping-cough and very intense catarrh, and in another a pleu- 
ritic effusion. Once it was remarkably hoarse, in a child at- 
tacked with measles, at whose autopsy we found an erosion of 
the vocal chords. 

An important fact to be noticed in the history of this symptom, 
is the period of its appearance. In children from two to four years 
of age, whatever were the circumstances under which the pneu- 
monia was developed, and whenever it has appeared under our 
observation, the cough has always manifested itself at least a week 
before the decided commencement of the inflammation. In older 
subjects, in cases of an idiopathic inflammation, the cough, the acce- 
leration of the pulse, and respiration, marked the opening of the dis- 
ease, while in the contrary case, when the affection complicated a 
catarrh, the cough was heard before the signs of the pneumonia 
were at all marked. 

The expectoration in our patients, from two to five years of age, 
was wanting, in the greater number of cases, and has been noted 
only (our times; in one it was sero-spumous, in two others sero- 
mucous, and in the remaining one sero-mucous, tino- e d with ver- 
milion-coloured blood. In those from six to fifteen years, it was 
nearly always present ; in seven cases the sputa were coloured, and 
ive times tinged with blood : in two cases of idiopathic pneumonia, 
they possessed the rusty tinge peculiar to the disease in the adult. 



We arrive, thus, at the same result as Dr. Gerhard, who, in twenty- 
patients, only met this kind of sputa three times. 

In the young children it was very difficult to assure ourselves of 
the existence of pains in any part of the chest, both from their want 
of the power of expression, and the difficulty of the appreciation of 
their existence by percussion. We have, however, assured our- 
selves of the presence of this symptom in three cases, in two aged 
four years, and another five: one of the two former had been 
attacked at the hospital with the disease, while in tolerably good 
health : in the remaining two, the inflammation supervened in the 
course of, or soon after, the measles. In the two former the pain 
was seated below the nipple, in the latter it was sternal, and, con- 
sequently, not corresponding with the pneumonia, which was situ- 
ated antero-posteriorly on the right, and postero'-inferiorly on the 
left side. In patients from six to fifteen it was more often noted, 
as we have encountered it twelve times. 

The epoch of the disease, at which the pain appears, is variable: 
sometimes it is the commencement, and, after a duration of some 
time, we have found, at the autopsy, old adhesions : at other times, 
the pain appeared at the end of the disease, or during the last days 
of life. 

This thoracic pain was not as characteristic, nor of as long con- 
tinuance, as in the adult: although really pleuritic, it has never, 
in our cases, lasted but from one to three days. 

The thorax in the greater part of our patients was well formed : 
we have, however, observed in four cases that the chest was con- 
tracted in front, and compressed on the sides, in a very sensible de- 
gree : these children were aged twenty months, and two and three 
years. In two other subjects the chest was remarkably arched in 
front. Rickets, so frequent in children, is the special cause to 
which we are to attribute all these alterations of symmetry; but it 
would be difficult to determine exactly the precise influence ot 
these deformities upon the production of pneumonia. 

In children from two to five years of age, the decubitus was 
either on the back, or indifferent; but we must mention that the 
two patients, attacked with the pleuritic pain, changed immediately 
after its invasion their mode of lying; thus— before, they lay indif- 
ferently on one side or the other, but afterwards one preferred the 
side of the pain, the other the opposite. In the children between 
five and fifteen years, the decubitus has offered nothing specially 
worthy of note. 

The respiration and the circulation were not the only functions 
offerino- remarkable disorders. The nervous system, so liable to 
impressions in the child, presented various lesions in two thirds of 
our cases— in all the young patients from two to five years, and in 
half of those from five to fifteen. 

In the former, the symptoms consisted most generally in an 
anxiety and an agitation, sometimes carried to extremes They 
showed themselves ordinarily at the commencement, and rarely 


continued throughout the whole of the disease. In the greater part 
of our patients this excessive anxiety was very well explained by 
the extent of the disease, occupying the greater part of the lungs; 
but in a child of two years, presenting only a few nodules of pneu- 
monia, it must be referred to the eruptive fever which coexisted 
with it. 

Other patients, far from presenting this agitation, offered a re- 
markable prostration and somnolence : in two of these cases the 
disease attacked in tolerably good health, and the hepatisation 
occupied all the lobe of one lung. 

The children from six to fifteen years, especially the youngest, 
presented sometimes an extreme anxiety, attended even with deli- 
rium : in other cases of the disease, complicating other affections, 
we observed a remarkable depression of the strength, frequent gid- 
diness, &c. In a young girl, aged fifteen, attacked with the pneu- 
monia during convalescence from typhoid fever, we observed the 
return of the typhoid cerebral symptoms at the same time with the 
development of the new inflammation. 

In a single case only have we been able to observe those symp- 
toms on the part of the nervous system, considered by some patho- 
logists as simulating a cerebral affection. These pseudo-meningites. 
appearing in the course of a pneumonia, are not so common as they 
have been hitherto pretended : and if we glance at some of the 
observations reported as examples of this particular form, we find 
many of them to be well-marked cases of typhoid fever ; for ex- 
ample, M. Leger's case, (pneumonia of the right side, with enteritis 
and ataxic symptoms.) Nevertheless, there do exist in the Gazette 
Medicale two or three examples of this particular form. Finally, 
in one of our younger patients, (a child of five years,) a pneumonia 
supervening in perfect health, assumed the typhoid character. 

Headach was inappreciable in the greater number of our pa- 
tients. Nevertheless, we have observed it once in the midst, and 
once at the commencement of the disease, both times in patients 
aged four to five years : five only of our older patients have made 
any complaint, nearly always at the commencement, and, at times, 
during the course of the disease. Of these five, four had idiopathic 
pneumonias, and the fifth a pneumonia accompanying measles. 
When the headach did exist, it was frontal, and was of no great 

In more than three quarters of the cases the digestive tube was 
in a more or less abnormal state. Most were attacked with diar- 
rhoea, slight in some cases, but more abundant in others, and con- 
stituting one of the affections during which the pneumonia fre- 
quently developed itself, (chronic enteritis.) The abdomen was 
without pain, tympanitic, or the contrary: the tongue, nearly 
always moist, was often covered with a white or yellowish 'coat. 

In two children, one aged three and the other four years there 
was slight spontaneous vomiting, but. only in the first day 'of the 
disease. We have seen the appetite persist in some children 


attacked with a pneumonia, which progressed very slowly, (it was 
of the simple lobular form in two of these.) In cases, on the con- 
trary, where the inflammation was extensive, and assuming a very 
acute type, the anorexia was complete, and in these also the thirst 
was extreme, far exceeding any thing of the kind in the adult : 
thus, we have seen young children swallowing with avidity every 
liquid that was presented to them, and only desisting from the 
necessity of respiration. 

In the older subjects the digestive tube has offered no remarkable 
symptom; thirst and anorexia have been noted in all the cases, and 
sometimes there existed vomiting. 

After thus enumerating one by one all the symptoms presented 
by the pulmonary inflammation of children, we ought to examine 
them grouped together, forming a single morbid entity. We should 
seek to sketch a picture of the disease, showing its diagnosis, and 
the march of its different varieties. This will form the subject of 
the following chapter. 



Before commencing this description, what shall be the elements 
of our divisions? Shall it be the pathological anatomy? Shall 
we describe, as have done all our predecessors, the lobular and 
lobar pneumonias as two distinct diseases? Or, imitating the ex- 
ample of Gerhard, shall we form two great varieties, dependent 
on the ages of the patients attacked by the disease? Or, further, 
shall we divide our patients into two categories, according as the 
disease attacks in full health, or supervenes upon some other affec- 
tion, which it complicates? 

The details into which we have already entered have shown us, 
that the two forms of pneumonia are confounded by very appreci- 
able gradations, and that the symptoms of a lobular pneumonia, be- 
come general through the lung, do not essentially differ from those 
of the lobar form : consequently, with the pathological anatomy for 
our sole guide, we should find ourselves obliged to divide very 
much our descriptions, for the same patient often presents on one 
side a simple lobular pneumonia, while in the other there exists the 
same form rapidly becoming general : now, how distinguish in the 
same patient the symptoms and the progress of these two diseases ? 

No more should age be the sole base of our divisions, since the 
study of symptoms demonstrates to us that the form assumed by 
the disease, and the progress that it follows, depend more upon the 
conditions in which it manifests itself, than upon the time of life 


at which it overtakes the patient. Finally, the mere consideration 
of the anterior state of the health will no* better assist us to class 
under one head all the varieties of the pneumonia of children. 

Adopting, then, no one of these divisions exclusively, we will 
lay them all under contribution— and desirous of presenting a 
complete picture of the disease, of producing the physiognomy and 
the particular expression of its different varieties; in fine, of giving, 
in a word, a description which shall enable all, now unacquainted 
with the pneumonia of children, to arrive easily at its diagnosis, 
we have thought best to establish the following species — two prin- 
ciples have served us for basis. The first, that the form of the dis- 
ease is dependent upon its exciting cause. The second, that the 
progress it follows partakes of the nature of the affection, in the 
course of which it is developed : thus, the simple lobular pneumo- 
nias become general, and the lobar pneumonias supervening upon 
a long-continued affection, are clothed with the particular attri- 
butes of chronic disease — while those, on the contrary, which arise 
in perfect health, or in the course of an acute disease, take to them- 
selves the acute characteristics. Hence two divisions. 

1. Simple lobular pneumonia, the lobular becoming slowly ge- 
neral, or the lobar form supervening in the course of a chronic 

2. The simple lobular, the lobular rapidly extending itself, or 
the lobar form attacking the patient in perfect health, or in the 
course of an acute disease. 

The first species is peculiar to the younger children, supervening 
generally upon the chronic ententes so common at that aofe, some- 
times after the exanthematous fevers, but in these latter long after 
the disappearance of the eruption. 

As it thus appears in patients, emaciated and enfeebled by long 
standing disease, ils external symptoms are not well defined. The 
cough is rare, sometimes even not present : the pain of the chest 
does not exist, the expectoration is wanting, the skin pale and cold, 
with oedema of the face and extremities : usually, however, at the 
moment when the disease tends to become generalised, there ap- 
pears a movement of reaction, manifested by an acceleration of the 
pulse and respiration, and an increased heat of the skin. 

The disease would, however, often continue completely latent, 
if auscultation, coming to our aid, did not reveal the symptoms of 
which a former full detail renders the enumeration unnecessary. 

Despite the diarrhoea often colliquative, the appetite frequently 
remains in full force, and the thirst is not augmented : the skin is 
covered with ecchymoses and furuncles. Ulcerations arise either 
on the nates or on blistered surfaces— the emaciation makes rapid 
progress and the patient succumbs in the last decree of maras- 
mus. & 

Of all its forms, it is when in the simple lobular state that the 
pneumonia is most difficult of recognition, but then also its diag- 
nosis is least important: supervening under the most unfavourable 


conditions, and at an epoch when disease has already undermined 
the powers of life, it adds but little to the gravity of the prognosis. 
Surely it well merits the name of asthenic, given by M. de la B^rge : 
but this appellation applies throughout its whole extent, without 
any particular reference to his supposed second period, which we 
confess has always escaped us. But even if we would establish 
two periods for the disease, the first should be the asthenic and the 
latter the sthenic, since, (as we have already explained) the reac- 
tion takes place in these cases only at the moment of the generali- 
sation of the pneumonia, and this generalisation is the last period 
of the disease, the one immediately preceding the fatal termination. 

2. The simple lobular, the lobular generalised, appearing in an 
acute disease, with the lobar species under the same circumstances 
or in perfect health, assuming an acute form, constitute our second 
division. They all follow the same course in children from two 
to five years: in those from five to fifteen they present some slight 
differences between themselves. 

The pneumonia of the former age presents two well marked 
distinct periods, the one, which may be called catarrhal, the other 

The catarrhal stage presents nothing constant as to its length of 
duration, but is always appreciable by its cough, generally not 
intense, slight alterations of the respiratory murmur, the sonorous 
or sibilant rales, the mucous cracklings, &c, without any accelera- 
tion of the pulse or respiration : the appetite is preserved, and the 
child still continues its sports, until finally there appears suddenly 
and simultaneously an acceleration both of the pulse and respira- 
tion, (marking the second period :) the skin becomes burning, the 
alee nasi are widely dilated, and there is an anxious expression of 
the face: the agitation, sometimes extreme, is replaced in other 
cases by a remarkable somnolence and prostration : the ausculta- 
tor in the first hours of the disease, recognises an obscurity of the 
respiratory murmur, or a subcrepitous rale, without appreciable 
dulness upon percussion ; later there appears a bronchial expira- 
tion, accompanied by the same rale, the bronchial character finally 
extending itself to both times of the respiration together with a no- 
table dulness upon percussion: the general symptoms preserve all 
their intensity as long as the pulmonary inflammation makes any 
progress. . 

At last the moment arrives when the pulsations and respirations 
become irregular, the pulse extremely weak, the face purple, the 
extremities cold : the prostration gives place to an anxiety in the 
whole performance of the functions, the cough ceases ; the young 
patients are attacked with prolonged gapings, uttering deep sighs, 
the pulse finally becomes insensible and death closes the scene. 
The progress of the hepatisation is sometimes so rapid as to pro- 
duce death in two or three days. 

In cases where the disease is to terminate favourably, the stib- 
crepitou- rale begins to reappear, the broi chial sound is limited to 


the summit of the lunar or the root of the bronchi, and the respira- 
tory murmur is again heard : while the local state is thus amelio- 
rating, the general symptoms lose their intensity ; thus, the pulsa- 
tions"and respirations are quickly diminished in number, the heat 
of the skin gives place to a pleasant moisture, with disappearance 
of the anxiety, &c. This resolution usually commences the seventh 
or eighth day, but even as late as the twentieth the last traces of 
the rale have not in some cases disappeared. 

These remarks apply specially to children from two to five years. 
In those from five to fifteen the differences in the progress of the 
pneumonia are somewhat important : it may attack in two circum- 
stances, — in the course of another disease, or in the midst of perfect 
health. In the former case if the malady which it complicates he 
catarrhal, we find the two periods much the same as in the younger 
class of children. 

If the pre-existing disease be not catarrhal, (typhoid fever, small 
pox,) the pneumonia is remarkable for its insidious approach, a 
cough is hardly present, the pain in the chest and the expectoration 
are entirely wanting ; and as the pulmonary affection is developed 
in the course of a febrile disease, we can with difficulty assure our- 
selves of the acceleration of the pulse or respiration. But there is 
one important symptom which may serve to arouse suspicion of the 
commencement of the disease — the deep change of the expression of 
the face, which we find noted in all our observations. 

The idiopathic form does not differ in a sensible manner from 
the same disease in the adult. It commences by fever, thirst, an- 
orexia, pain in the head, cough, pain in the chest, and sometimes 
vomiting : auscultation discovers a crepitous rale, bronchial respi- 
ration and bronchophony ; the expectoration is often bloody but 
rarely rusty ; the acceleration of the pulse and respiration is con- 
siderable. The nervous symptoms are sometimes rather pro- 
nounced, and we observe intense headach with anxiety or even 
delirium. According to Gerhard and Rufz the mean duration of 
this form is fourteen days. In the few cases we have seen, it has 
been much longer; one of our patients quitted the hospital the 
twenty-first day of his disease with the bronchial respiration still 
present; and in another the subcrepitous rale, which had succeeded 
it, endured six weeks. 



After this exposition of the symptoms to assist us in the recogni- 
tion of the pneumonia of children, let us see if there be no danger 
of confounding it with any other disease of the respiratory organs. 



For example, what are the differences between pneumonia and 
pleurisy, bronchitis and phthisis. "Simple pleurisy is a very rare 
disease in children from two to five years ; for our part, we have 
never met it, for whenever we have found a liquid in the pleural 
cavity, there has always existed an hepatisation of the Lung, thus 
usually confounding the symptoms of the pneumonia with those of 
the pleurisy. In one case the absence of all respiratory sound, 
where a bronchial respiration had been heard, immediately after 
the declaration of a pleuritic pain, enabled us to recognise an effu- 
sion complicating the hepatisation. We may also remark, that the 
access of suffocation, mentioned in two of our observations, ap- 
peared of some value as diagnostic of an effusion into the pleura, 
cavity. But we must not assign too much importance to this 
symptom, as we are not certain that a rapid hepatisation may not 
give rise to the same phenomenon. Among the observations of 
MM. Constant and de la Berge, we find two of a pleuritic effusion 
diagnosticated by percussion and change of position. 

In the older children, simple pleurisy is still a rare affection, dif- 
fering however in nothing from the same disease in the adult. 

A bronchitis severe enough to produce constitutional symptoms 
is certainly very rare in children from two to five years. In the 
immense majority of cases, when it puts on this form, it is compli- 
cated with lobular pneumonia, and we have, in speaking of the 
diagnosis of this latter, alluded to the great difficulty of distinguish- 
ing these two affections, especially where the bronchial element is 
predominant. A catarrh in the younger children not determining 
any symptoms of reaction is characterised by cough, sonorous and 
sibilant rales, mucous cracklings or even the subcrepitous rale, but 
this latter is in general of short duration and its bubbles are very 
unequal. As we have often heard a subcrepitous rale in cases 
where we have afterwards found pneumonia, we would guard 
against being understood to assert a subcrepitous rale heard on both 
sfdes of the back to be a pathognomonic sign of bronchitis, such 
an assertion would be in flagrant contradiction to facts, which we 
have detailed above. 

In children from rive to fifteen years, a pulmonary catarrh fre- 
quently complicates other affections, measles, hooping-cough, 
typhoid fever, &c, but it is also observed idiopathically, and then 
it presents no difference in its symptoms with that of the adult. 

The tuberculous affection of the lung ; can this simulate a pneu- 
monia? In speaking of vesicular pneumonia we had occasion to 
remark that a superficial examination might mistake the granula- 
tions of inflammation for those of tubercles, and we have thus 
pointed out their characteristic differences. Inattentive observers 
also might regard the small abscesses of the lung as tubercular 
excavatTons, but in those latter when existing in the parenchyma, 
the surrounding tissue and the age at which they occur prevent all 
mistakes of this nature. In fact we all know that in children, of 
16-d ril 4 


two or tiiree years, the tuberculous affection is rare, and that in the 
cases where it is found to occur, the tubercles have never advanced 
beyond the crude state. In older subjects, phthisis becomes ex- 
tremely frequent, but its chronic character most generally diagnos- 
ticates it from pneumonia. The diagnosis however is often very 
obscure, especially when we are deprived of an accurate informa- 
tion of the origin and progress of the disease. — To choose some 
examples illustrative of this subject. A child has the skin hot, an 
intense fever, dulness on percussion, and bronchial respiration un- 
der one of the clavicles. Is it attacked with pneumonia ? We have 
frequently seen this question decided in the affirmative and a treat- 
ment, consequent upon such a view, applied to the case ; but ne- 
vertheless the autopsy has proved these symptoms, in the great 
majority of the cases, to be dependent upon a tuberculous infiltra- 
tion of the lung. Besides such a diagnosis might be given a priori. 
as a glance at our table of the seat of the lesions shows only two 
cases of pneumonia limited to the anterior portion of the lung, and 
only one of hepatisation immediately beneath the clavicle. The 
signs of an idiopathic pneumonia under the clavicle, although rare, 
do sometimes exist, when this affection is developed in a tubercu- 
lous subject. And as the young patients are often brought to the 
hospital for the complication alone, with the very incomplete in- 
formation we can obtain of the former health, we might easily 
overlook the original disease, and give a prognosis founded on too 
favourable a view of the case. In these difficult cases great regard 
is to be paid to the intensity of the febrile movement, and the pro- 
gress of the disease. Thus, a persistence of the physical, after the 
decline of the rational, symptoms is very probably due to a tuber- 
culous affection. But finally, when the tubercles, surrounded with 
the pneumonia, exist at the posterior part of the lung, the difficulty 
of the diagnosis increases greatly, from the doubt created by the 
seat of the disease. 

And this is not all ; when the tuberculous affection, instead of 
being confined to a limited space, is scattered profusely through 
the whole parenchyma, as is so common in the acute phthisis of 
children, the diagnosis is far from being clear. Thus, in those 
cases of equally disseminated tubercles, without any surrounding 
pneumonia or bronchitis, we have many times found no other phy- 
sical signs than a rudeness of the respiratory murmur ; and if there 
be bronchitis or presence of mucus, we have a mucous or subcrepi- 
tous rale ; very nearly the same symptoms as in the simple lobu- 
lar pneumonia. Now as this latter affection, as well as phthisis, is 
the frequent successor of measles, we can, in such a case only 
form our diagnosis upon the collateral evidence and the final pro- 
gress of the disease. Suppose, in a case of hereditary predisposition 
to tubercles, we observe, after measles, that the cough continues, 
that for a month after there is still heard the mucous^rale and that 
the child emaciates with an attack of fever, each evening ■ with 


these symptoms alone we might suspect the existence of tubercles. 
If, however, after the measles in a healthy well constituted child, 
there still exists a violent fever, cough, mucous or subcrepilous 
rales, succeeded by an expiration and then bronchial respiration, 
we might believe in a lobular pneumonia which has finished by 
becoming general. We see, therefore, there are many cases where 
error is easy, and we ought to suspend our diagnosis till after some 
days' examination. 

Finally in a last case, the difficulty of the diagnosis depends 
no longer merely on the combination of the phthisis and the pneu- 
monia, but lies entirely in the particular form of this latter affec- 
tion. If, in fact, we recall the particular character given to our 
first species, we shall recognise in them nearly all the symptoms of 
phthisis arrived at its last degree. The cough, the colliquative 
diarrhoea, the extreme emaciation, the paleness of the skin, the 
infiltration of the extremities, &c, what are these but the collection 
of symptoms assigned by all pathologists to the tubercular disease, 
in its most advanced stage. Despite an appearance so deceitful, 
however, the diagnosis will not be very difficult, since it must be 
one of two things ; either the pneumonia will be simple, and then, 
the physical signs bearing no proportion to the gravity of the con- 
stitutional affection, will indicate that we have to do with a limited 
affection of the lung, as a tubercular disease accompanied by such 
grave general symptoms presents ordinarily physical signs indica- 
ting 1 a considerable alteration of the pulmonary parenchyma, or 
else the pneumonia will have passed to a generalisation and as- 
sumed the lobar form, and the stethoscope will inform us that the 
disease exists at the posterior part of the lung, is double, &c. &c. : 
in a word, we shall recognise by it all the signs of a pneumonia. 
The progress of the malady will also present various differences 
between the two diseases ; thus, generally the diarrhoea precedes 
the cough in the pneumonia, while in phthisis it appears at a 
period more or less distant from the commencement of the disease. 
And to conclude with the final difference, we will cite the age at 
which both the affections are developed. Our first variety of pneu- 
monia is most often met with in children of two and three years of 
age, while at that period of life pulmonary phthisis is very rare. 



The gravity of the prognosis varies with the age and the different 
forms of the disease. It may be advanced, as a general proposition, 
that a pneumonia is the more dangerous in proportion to the youth 
of the patient. Our tables very manifestly prove this, and the re- 


searches of MM. Valleix and Vemois, at the Hospital of the Enfans- 
Trouves o-ive a further weight of evidence to this assertion. As 
to the influence of the different forms, the pneumonias of our first 
species are grave in consequence of the disease which they com- 
plicate. They are, in fact, nearly necessarily mortal. Grounding 
upon the experience of our predecessors, and upon our own in par- 
ticular, we would call them always fatal, if it were not for a re- 
markable case before us, of recovery in a child placed under the 
most unfavourable circumstances. 

The secondary forms of pneumonia are, at all ages, of an ex- 
treme gravity: thus, of eighty-one pneumonias, complicating very 
various diseases, observed in our service in lb37, seventy-seven 
have terminated fatally. The pneumonias in the youngest chil- 
dren, supervening upon a good state of health, or merely upon a 
slight catarrh, most usually recover : eight patients, from three to 
five years of age, have recovered from the disease under these cir- 
cumstances. And. finally, the inflammation of the lung, in children 
from five to fifteen years, occurring in good health, arrives, in the 
immense majority of cases, at a happy issue. All the patients of 
this latter category have recovered: this result, based on so few 
facts, might be contested, if other observers (Gerhard and Rufz) 
had not arrived at the same conclusion, after an examination of a 
much larger number of cases. 

A general prognosis from the study of the circumstances of the 
developement of the disease being thus established, it remains to en- 
quire if particular symptoms indicate, in any positive manner, a 
greater or less gravity of the affection. The state of the pulse is one 
to afford us the greatest aid. Its acceleration is generally in a direct 
proportion to the intensity of the disease: but, in addition, at an 
advanced period of the malady, we have observed a character 
already mentioned, but upon which we would especially insist in 
this connection, viz: the smallness of the pulse. Every time, when 
this has been noted, death has not failed to appear in a few hours, 
or a couple of days at the utmost. The cessation of the cough, the 
chilliness of the extremities, the purple hue of the face, coincide 
ordinarily with this smallness of the pulse, and announce a speedy 



The therapeutical is, without dispute, of all parts of a monograph, 
the one meriting the most serious attention. The final end of all 
medical research, it constitutes the only portion really practical. 


Therefore, in the study of the treatment, we have not confined our- 
selves solely to onr own observations, but have laid under contri- 
bution those of our predecessors. Unfortunately, too often their 
assertions are contradictory, and their opinions without proof. 

In the hope that an examination of particular facts might throw 
some light upon this present question, we have analysed, with a 
special care, nearly ninety observations, inserted in different jour- 
nals of medicine, or in the different monographs already alluded to: 
but we have to regret the little fruit of our labour, in consequence 
of the lamentable deficiency of detail. 

In the interpretation of facts, as also in the estimation of the the- 
rapeutic value of our observations, we have adopted the following 
method : — after as complete as possible an assurance of the proper ad- 
ministration of the remedy, we have endeavoured to appreciate its 
influence upon the progress of the disease, and we have laid parti- 
cular stress upon the period at which the treatment has been com- 
menced. „ 

The comparative variations of the pulse and respiration, together 
with the physical signs, have served us to denote the increase or 
decrease of the disease. We have, besides, examined the action of 
the remedy, considered both in the first dose, and after a continua- 
tion of several successive days. And, finally, in the appreciation of 
the final result, (death or recovery,) we have taken into the ac- 
count, as an essential element, the nature of the pneumonia which 
we had had to treat; for, if our details upon the subject of prog- 
nosis be remembered, the reader will recollect the immense influ- 
ence upon the termination of the disease exerted by the conditions 
of its development. 

With the exception of some particular medication, exacted by 
special indications, the treatment has always been composed of two 
parts : one common to all diseases, (hygiene,) the other special to 
the disease before us: we commence with this latter. 

The principal measures directed against the inflammation have 
been, I. Bleeding; 2. Antirnonials ; 3. Derivatives applied to the 
cutaneous system. 

We shall first examine the effects of the separate employment of 
each of these remedies, and then the influence of all combined. 


Opinions of authors vary much as to the influence of bleeding 
in the pneumonia of children. Thus, some proscribe it absolutely, 
while others make it the basis of their treatment. Some prefer 
o-eneral, others local bleeding. It should be remarked, that those 
employing the bleeding, dread to carry it too far, lest the patient 
may never recover from the collapse. We have cited, however, an 
observation (perhaps unique in science) of a child treated by the 
formula of repeated venesection. A favourable issue, however, in 
this single case would not induce us to dare to imitate such an ex- 


periment. It must be remembered, however, that the child, though 
only aged two years, was in perfect health at the commencement 
of the disease, and, therefore, in the most favourable situation : and 
further, when we scrutinise the details of the case, we find the 
amelioration to have commenced only the seventh day from the 
invasion, that is to say, the bleeding does not appear to have sen- 
sibly advanced the epoch of the usual resolution of the hepati- 

Having just said that practitioners did not push very far the loss 
of blood, we give here their usual method. In children from two 
to four years, local bleedings are generally alone employed, either 
by leeches or cupping glasses. At this age, twelve or fifteen leeches, 
three or four times repeated, are the usual extent. In older child- 
ren, they employ bleeding from the arm proportionate to the age 
of the child and the intensity of the disease ; thus, in a child from 
five to eight years, four to eight ounces of blood at once: in those 
from eight to fifteen, eight to twelve ounces. 

In some particular observations, this moment under our eyes, 
(Gazette Medicale,) we noticed bleeding to nine ounces, repeated 
twice, thrice, and four times in children from twelve to fourteen 

After this general indication of the methods of different prac- 
titioners in the employment of this remedy, we will discuss the 
efficacy of such a treatment. Here we shall find a wide difference 
between the idiopathic and the complicated pneumonias. Ger- 
hard thinks copious bleedings may be of advantage in the idio- 
pathic pneumonia of children from six to fifteen years. He has 
remarked the immediate effect to be a diminution of the intensity of 
the general symptoms, (headach, agitation, oppression, &c.,) with- 
out, however, any appreciable influence upon the duration of the 

The analysis which we have made of different observations does 
not comprise all these results: we find in many the bleedings, even 
copious, to have had not only no appreciable effect on the pulse or 
respiration, but also none upon the patient's general condition. 
Thus, M. Blache has inserted, in the Archives de Medecine, (1837,) 
several cases of pneumonia, in which no amelioration whatever 
followed the loss of blood. Besides, we may make this general 
remark, that the amendment in the symptoms succeeds rarely to 
the first bleeding, but follows only the second or third, at a time 
corresponding to the seventh and ninth days of the disease. We 
may, therefore, establish as a principle, that, although of some ad- 
vantage in idiopathic pneumonia, the utility of bleeding appears 
restrained within very narrow limits. 

If, now, we attempt an appreciation of its influence in the com- 
plicated species of the disease, we shall be struck with its want of 
influence not only upon the termination, which is nearly always 
fatal, but also upon the progress of the disease, which undergoes no 
sensible modification. If proofs are sought, we have only to o-lance 


at the observations, by M. Blache, of pneumonia complicating 
noopin^-congh, to read the reflections of M. Baudin on the treat- 
ment of the disease after measles, or consult many other observa- 
tions scattered in the different periodicals, and we shall be terrified 
with the immense proportion of the mortality, and the complete in- 
efficacy of the subtraction of blood. 

We may add, in confirmation, that M. Becquerel, who made his 
observations in a service where this mode of treatment was solely 
employed, has never seen a case of recovery in the disease, com- 
plicating a pre-existing- affection. 

To give some idea of the action of bleeding, we will report suc- 
cinctly the history of three of our patients, the only ones submitted 
to this treatment. Their ages were two, five, and six years: in 
the first two the disease was developed in tolerable health, in the 
third it complicated a hooping-cough. In the first, (the child of. 
two years ) on the sixth day of the disease, five leeches were ap- 
plied to the right side, the bites of which furnished an abundant 
quantity of blood. On the morrow there was a sensible ameliora- 
tion, the pulse had fallen from 160 to 120; the bronchial respira- 
tion and the dulness on percussion, which before occupied the 
whole of the inferior lobe, were much scattered ; the coloration 
of the countenance gave place to paleuess; a calm succeeded to the 
agitation, <fcc. 

The child of five years was bled, the sixth day., to six ounces, 
when the pulse was 140, the respiration 36, and a bronchial respi- 
ration existed in the middle third of the ri^ht lung: the morrow, 
seventh day, the respiration was bronchial in both its times, the 
percussion but slightly resonant in these points, the pulse 120, 
respirations 44. Six leeches were applied to the right side. The 
eighth day the pulse was 120, the respiration 34, and the bron- 
chial respiration was heard in the whole height of the lung. The 
ninth day, pulse 120, respiration 34, bronchial respiration limited to 
the summit, with subcrepitous rale beneath. The tenth day, pulse 
100, respiration 28, bronchial respiration at the summit, &c. 

In these two cases there appears to have been some influence 
exerled upon the progress of the disease. But it should be remarked 
that if, in the first, the amelioration succeeded immediately the ap- 
plication of the leeches, it was only definitive on the seventh day, 
that is to say, at the very time when the pneumonia, supervening in 
good health, has the greatest tendency to assume, of itself, a favour- 
able change. 

In the second, the resolution of the pneumonia appeared only the 
ninth day, despite the bleedings of the sixth and seventh. And as 
to the final result, (recovery,) we must recollect that our patienls 
were both placed in very favourable circumstances, and in a class 
of the disease nearly always terminating in health. 

Our third child was not in the same condition : the pneumonia 
appeared in the midst of a hooping-cough, or rather of a catarrh, 
with very intense paroxysms, and the disease had already deter- 


mined a formidable constitutional reaction when the inflammation 
of the lung was developed : so great a loss of blood, (one bleeding 
of six ounces, and twenty-two leeches applied at different times,) 
exerted no influence upon the pulse, respiration, or march of the 

Antimonials — Tartar Emetic. 

In the examination of the effects of antimonials, and of the tartar 
emetic in particular, we were obliged, from the complete want of 
published facts, to have recourse solely to our own observations. 
We find, it is true, many cases in authors, entitled cure of pneu- 
monia by tartar emetic, but in nearly all, bleeding - has been em- 
ployed in concert, constituting the mixed method, of which we 
shall soon have occasion to speak. 

Nine of our patients took the tartar emetic carried to a high dose. 
Six of them were aged from two to six years, three from eleven to 
fourteen. The portion given to the youngest contained three and 
four grains. 1 in five ounces of the vehicle; for the older, the dose 
was five to six grains. They took a spoonful every two hours, and 
when the first produced vomiting, they delayed the following doses: 
in general, a tolerance was quickly established, though sometimes 
we had to encounter vomitings, and, in one case, a somewhat pro- 
fuse diarrhoea, lasting several days. 

The vomitings seldom endured after the first dose, or, in general, 
they were not numerous, and ceased sometimes even under an in- 
creased dose of the remedy. We have never seen any accidents 
from this medicament, except in two cases of a pustular inflamma- 
tion of the fauces. This inflammation, due entirely to the local 
action of the remedy, and so frequent in the adult, has been ob- 
served in nearly all the patients of this year, treated with the tartar 
emetic: it presents no particular gravity, and yields usually in 
young children, as well as in older subjects, to the simple emol- 

What has been the influence of the tartar emetic upon the termi- 
nation and the principal symptoms of the disease? Of nine patients 
four have recovered, and two of these under rather unfavourable 
circumstances: thus, one had a pneumonia after small-pox, the 
other a double pneumonia, complicating the measles. Our third 
was a child of three years, attacked from the commencement with 
a slight catarrh and a chronic eczema : and, finally, the fourth case 
of recovery is a young girl of eleven years, of a scrofulous consti- 
tution, but otherwise in good health at the commencement. Two 
of these commenced the treatment the first day, the other two at 
the sixth day only. The whole quantity taken by each has varied 
from sixteen to twenty-four grains. In these four patients the 

1 In giving the amount of doses of medicine, the quantity per diem is in- 
tended, this being tlie form of prescription in the Parisian hospitals. P 



emetic tartar appeared to exert some influence upon the pulse and 
upon the respiration, but this influence has not been in all the cases 
durable, and in three of the cases it manifested itself nearly at the 
same epoch in all, viz: from the seventh to the ninth day of the 
disease. As to the patients who succumbed, they were placed in 
the most unfavourable circumstances: three were already attacked 
with measles and with typhoid fever, and the remaining one was a 
child of two years, with a double pneumonia complicated with a 
pleuritic effusion. We have, however, been able to remark a de- 
cided influence upon the pulse and respiration, even in those of 
the fatal cases, where the dose was a little elevated : but there 
was no decided effect upon two patients who took only six grains. 

If we sought to draw any general conclusions from this small 
number of facts, we should say, but with reserve, from the small- 
ness of our numbers, thai the tartar emetic may be employed with 
success in the child; that there is no danger in a somewhat ele- 
vated dose ; that the tolerance is generally easily established ; that 
the gastro-intestinal accidents give little cause of fear ; and. finally, 
that this medicament appears to act more directly Upon the puhe 
and respiration than upon the hepatisation itself. 

The combined Method of Treatment, Bleeding and the Tartar 


After this attempt at a separate estimation of the value of bleed- 
ing and the tartar emetic, we will examine their combined influ- 
ence upon the disease before us. We have discovered in various 
authors thirteen cases, giving somewhat circumstantial details upon 
this mode of treatment: In all these cases the tartar emetic has 
been given after more or less copious bleeding, and at some dis- 
tance" from the commencement of the disease. All the patients 
thus treated and attacked with idiopathic pneumonia, (aged from 
nine to twelve years,) have recovered, with the single exception of 
one, who succumbed, with a eangrene of the mouth supervening 
upon the pneumonia. Two children, in whom the pneumonia was 
developed around a tuberculous affection, have died although in 
one of them there took place a very sensible amendment of the 
symptoms after the first dose of the antimony. As to the influence 
of this method of medication upon the progress of the disease, it 
has appeared to us, after an attentive perusal of the foregoing ob- 
servations, that the combination of the two methods exerts a more 
decided influence upon the general and local symptoms than the 
employment of either one separately. Thus, although in general 
the amelioration appears from the seventh to the ninth day as in 
the cases treated by the tartar emetic simply, we find in two or 
three cases an amendment of the symptoms on the hfih or sixth 
dav : and more than this, in all the cases, even in those terminating 
fatallv a diminution of- the pulse and respiration succeeded the 
first dose of the medicament, whatever was the period of the dis- 


ease at which it was employed. Three of our patients were sub- 
mitted to the com'aned treatment of hleeding and antimonials: all 
three were bled once or twice, and took besides, one the tartar emetic 
another kermes mineral, and the third both the tartar emetic and 
the kermes. The tartar emetic was always given in the dose of 
one or two grains in a large quantity of water as vehicle, and 
determined numerous vomitings. The three patients submitted to 
this treatment recovered, but the pneumonias were all idiopathic 
and the amelioration took place from the seventh to the ninth day! 
The facts already published are by no means sufficiently nume- 
rous to decide the grand question of the mode of action of the tartar 
emetic. Is it by absorption, or does it merely determine, by the 
vomitings, a salutary revulsion upon the digestive canal? Both these 
hypotheses are, perhaps, just; in some proof of which, on the one 
h;md, the emetic tartar carried to a large dose, without vomiting, ap- 
peared to have exerted a happy influence upon the disease— while, 
on the other hand, a rapid amelioration followed its employment in 
doses producing vomiting in two or three patients, whose cases 
are now before us. In several of these cases, the analysis of which 
forms the basis of this article, we see that the dose of the emetic 
was sometimes carried to a great extent— thus, a child of fourteen 
years took, in all, one hundred grains, and even as high as ten 
grains, in the twenty-four hours; another, aged nine years, took 
daily from six to eight grains, &c. &c. In aU cases not the 
least accident has resulted. 

White Oxide of Antimony— Pulois Anlimonialis. 

Eighteen of our patients were treated with this' medicament ; ten 
in large doses, and eight in small. We have but little to remark 
upon these latter cases, as the remedy was never given at the com- 
mencement, nor throughout the whole disease. In these eight, 
the dose per diem varied between ten and eighteen grains in four 
ounces of vehicle, to which was added 3ij. or #1 j. ofsymp of dia- (syrup of poppies.)' All these children, except one, are 
in our first d.v.smn-that is, pneumonia supervening upon some 
chronic affection. Two of these recovered, but this cannot be 
attributed to the remedy ; in one case it was not commenced till 
he ninth day, when the pneumonia already tended to a resolution, 
whilst ,n the other, a child of eleven years, attacked with small- 
pox,) it was administered for only a single day 

Of the other ten, we must eliminate two, who, dying the day 
after their entrance of very extensive pneumoniae, took, conse- 
quently, only one potion of the remedy. The pulvis antimonSL 
was administered to children between two and five years of age!

United States Dispensatory, resembles the syrup ? En ? ^Z '. n lh * 
to be considered as identical with \t.—P. YlP diac °dium sufficiently 



One other, aged six and a half years, who was attacked with a 
general capillary and vesicular bronchitis, cannot, consequently, 
be included among the pneumonias. 

The powder was given in emulsion or mucilage, in the dose (for 
children of two and three years) of half a dram in the twenty-four 
hours, carried as high as a dram and a half, or even two drams. 
Children of four and five years took from one up to three drams, 
or even half an ounce. 

Of these eight patients only one recovered, who had a lobar 
pneumonia involving the whole lobe. Of the others there was, 
perhaps, only one susceptible of recovery, judging- from the pro- 
gress of the disease, the pathological anatomy, and the absence of 
complication. The influence of this medication has appeared al- 
most nothing upon the pulse and respiration, whether after a single 
dose, or many days' employment : if sometimes the pulsations did 
diminish in number, at others they increased, or remained the same. 
The same remark applies to the respiration, the variations of which 
presented no accordance with those of the pulse. But, upon the 
progress of the disease its influence was still less— in almost no 
case was there a sensible amelioration. In the only patient who 
recovered it was after the sixteenth dose, (the eighth day,) that the 
alteration for the better manifested itself, and the disease lasted, in 
all, eighteen or nineteen days, which would seem to indicate no 
abridgment from the pulvis antimonialis. However, the following 
happened in one of our patients : after the first dose, the pulse in- 
creased from 120 to 150, the respiration from 46 to 50, the physical 
signs remaining the same; but, after four days of its administration, 
an amelioration was declared in all the symptoms, the pulse fell 
30 beats, and the inspirations instead of 50 were 44 : and the aus- 
cultation confirmed this great amelioration. The dose of the 
powder was diminished, and the next day all the symptoms re- 
appeared as violent as ever. It was increased again, the pulse fell 
to 100, the respiration to 34, without any sensible amelioration in 
the physical signs: the amendment, however, did not continue; 
all the symptoms were soon aggravated ; and death did not delay 
its appearance. • 

In this case, if the pulvis antimonialis really did exert no mani- 
fest influence, at least the coincidence between the administration 
of the remedy and the amelioration of the symptoms is a little re- 
markable. . ... , ... 

We have never observed any action of this powder upon the 
digestive tube, nor any accident from its employment. It must be 
allowed to have the power of slightly exciting the gastric mucous 
membrane, since in two of our patients treated the one with high 
and the other with small doses, and in whose stomachs, at the 
autonsv we found some of the powder, there existed patches of red- 
ness, more or less vivid, at those points where it was in contact with 
the mucous membrane. 


The different observations published upon the employment of the 
antimonial powder in the pneumonias of children do not at all con- 
tradict the results at which we have arrived. In many of them we 
can discover no influence of the remedy upon the pulse, respiration, 
or the inflammation itself; and in many, where its influence upon 
the progress of the disease is vaunted, it would seem impossible to 
decide whether the amelioration was due to the remedy, or whether 
nature herself had not performed the cure, the precise period of the 
commencement of the disease not being indicated in the observa- 

It must be remembered that all our patients except in the case 
of recovery, were in the first category, that is, of pneumonias ac- 
companying some other grave disease, which are very universally 

Precipitated Sulphuret of Antimony. — Kermes Mineral. 

We have no where found any detailed observations upon the 
use of the kermes mineral in the pneumonia of children ; we must 
therefore have recourse solely to our own observations. Fifteen 
patients were treated by this medicament : of these we must elimi- 
nate four, to whom it was given in a small dose, as adjuvant merely, 
and not forming the basis of the treatment, and three others, in 
whom the disease was already too advanced to hope for any relief, 
death supervening the day of the commencement of the treatment. 

The remaining eight patients were aged between four and four- 
teen years, embracing therefore pneumonias of all the ages and 
species. The kermes was administered in doses of one and two 
grains to commence ; and was carried successively to twelve, fif- 
teen or even seventeen grains in the twenty-four hours, augmenting 
a grain about every visit ; of these eight patients, three recovered, 
from an inflammation of all one lung, or a lobular pneumonia. 
Among the other five, there was only one perhaps capable of re- 
covery, since he alone had no primitive grave complication : his 
pneumonia was well marked lobular, but so extensive at the day 
of entrance, that a fatal termination' was prognosticated from the 

If now we attempt to seek the influence of the kermes upon the 
pulse, respiration, and stethoscopic signs, we find these three 
symptoms in some cases increased, in others diminished, and in 
others remaining stationary. The general idea, however, which 
remains after an examination of the result of the treatment in all 
these patients, is that the kermes has exerted a favourable influence 
more often than otherwise, and therefore that it is a tolerably effi- 
cient remedy. But if we come to the analysis of each separate 
fact, we find that the cases, where the symptoms were aggravated 
after several days of treatment were precisely those where the 
pneumonia was of our first species, and therefore almost necessarily 
fatal. Among those on the contrary, terminating in health, are 


found the idiopathic and lobar forms, free from all complication, 
where, according to Gerhard and Rufz, recovery is certain what- 
ever may be the treatment. Besides a certain number of our pa- 
tients have entered when the disease had reached its maximum of 
intensity, and when an amelioration after the first dose of kermes 
is rather to be attiil.nted to the arrival of the disease at its natural 
climax. Thus a child of four years was submitted to our observa- 
tion the seventh or eighth day of an idiopathic lobar pneumonia 
with pure bronchial respiration ; he took a grain of kermes and the 
next day he had the returning crepitous rale, and two days after a 
diminution of all the symptoms. Is the amelioration to beattrihuted 
to the kermes taken these three days, or to the natural progress of 
the disease? The latter appears to us the more probable. Observe 
in fact, that in all our cases of supposed beneficial effects of reme- 
dies, it is always at the same period of the disease that the amelio- 
ration manifests itself — from the seventh to the ninth day — we 
cannot, however, refuse to admit some influence to the kermes, as 
we have established its power in diminishing the pulse and respi- 
ration in several cases, both immediately after the first dose, as well 
as after several days of treatment, in patients gravely affected, and 
attacked with complications finally resulting in death. We possess, 
besides, one case of recovery in a lobular pneumonia after measles, 
under the sole use of the kermes: and this pneumonia although 
exempt from any unfavourable complication, was not the less 
grave, considering the cause to which it owed its birth. 

In some cases the kermes has been administered at a very high 
dose, especially for a child. Seventeen grains are more than is 
habitually given loan adult; a dose apparently so enormous has 
had no unpleasant influence upon the digestive organs ! Here is the 
result of our experience. 

Our patient, who took the seventeen grains, and who recovered, 
presented before the administration of the kermes, some symptoms 
referable to the digestive tubes — bilious vomitings, diarrhoea, and 
abdominal pains. These symptoms underwent no augmentation 
under the increasing doses ; after about fifteen days they ceased 
altogether, although the patient was then taking thirteen or four- 
teen grains in the twenty-four hours. 

In another who took fifteen grains and who died, we observed 
before the first dose the same symptoms connected with the intes- 
tinal canal ; but these symptoms increased with the inflammation 
of the lung, and at the autopsy we found an inflammation of the 
gastric mucous membrane, slight in extent it is true, but very well 
maiked, especially where there yet remained a portion of the 
kermes. We have never observed any other accident requiring a 
suspension of this treatment. 

To conclude the history of the kermes mineral, we give a suc- 
cinct extract from the observation of one of our patients treated by 
bleeding the tartar emetic and this latter substance; the reader 
may thus judge of the combined action of the three. 

62 rilliet and uaktiiez on pneumonia op children. 

It is the case of a child aged ten years, at the fifth day of a pneu- 
monia of the lower half of the left lung, with bronchial respiration, 
absence of rale, and dulness upon percussion. Infusion of mallows, 
syrup of gum ; with gr. ij. tartar emetic, looch, 1 bleeding to eight 
ounces, diet. The tartar emetic thus administered produced fre- 
quent vomiting, and on the morrow the pulse had augmented from 
122 to 152; the inspirations had diminished from 82 to 62, the 
bronchial respiration had extended a little superiorly, but a crepi- 
tous rale was heard after cough inferiorly. This first prescription 
had at once augmented and ameliorated the gravity of the symp- 
toms. (Infusion of mallows, syrup of gum, looch, with kermes gr. 
ij. the half of an emollient enema, diet.) 

The day after this first administration of the kermes, seventh 
day of the disease, diminution of the bronchial respiration, more 
abundant rale, the inspirations have fallen from 60 to 36, the pulse 
from 132 to 96. The treatment is continued with the addition only 
of a bouillon. But on the eighth day the rale had disappeared, the 
bronchial respiration was in the same extent, the pulse was 150, 
the respiration 36. (Emetised whey, gr. ij. ; blister to the legs.) 

The following day the bronchial respiration had extended, but 
there was but little ia!e ; respirations 50, pulse 132. This day the 
kermes was resumed in a dose of two grains, with one half an ounce 
of syrup of poppies. The disease continued augmenting, till the 
thirteenth day, when the patient took five grains of kermes. But 
the fourteenth day, the bronchial respiration was less, the crepitons 
rale of return again appeared every where. 

From this moment the patient continued improving until com- 
plete convalescence, and on the nineteenth day the respiration was 
pure on both sides. The kermes was continued a few days after 
this happy result. We see, in this case, only a dubious salutary 
influence of the bleeding and tartar emetic, as it was only on the 
seventh day of the disease that an amelioration took place ; the 
kermes was not sufficient to continue this improvement, and a re- 
lapse was the consequence. The tartar emetic was again given, 
with a similar result, and it was only on the fourteenth day of the 
disease, the sixth of the relapse, that the patient was definitively 
belter under the influence of the kermes. Should we in this case 
attribute the cure to the remedy, or shall we think that the disease 
has followed its own course without any regard to its influence? 

Derivatives to the skin — Vesicatories. 

Vesicatories have been employed in conjunction with the other 
remedies and nearly always at an advanced period of the disease. 
They have been applied either to the diseased side or to the ex-

cantli: it is entirely demulcent.— P. & b 


tremities. They have not appeared to modify the course of the 
affection, and they have caused the patient such inconvenience, as 
ought to proscribe their employment. In fact the skin of the pos- 
terior part of the thorax, in contact with the soiled linen, com- 
pressed by the projecting ribs, excavates and ulcerates, in a manner 
very painful and difficult to heal, and adding still more to the 
gravity of the prognosis. It is especially with regard to the pa- 
tients in our first category that we have made this remark, which 
besides has not escaped M. de la Berge. 

These remarks upon blisters are equally applicable to the Bur- 
gundy pitch plasters sprinkled with the tartar emetic, which have 
been applied to some of our patients. 

We should not forget among the revulsives, the cupping glasses 
which we have seen applied in some cases. Ordinarily dry cup- 
ping only is employed in the younger children ; in the older, how- 
ever, the scarificators were added, thus answering the indications 
of a local bleeding, and a derivative. The cases of the employment 
of these means are too few to estimate their therapeutic value. 

In concluding this history of the different active agents put in 
force against the pneumonia of children, we will still revert to a 
general remark upon which we have always insisted, viz : that the 
first signs of amelioration appear in nearly all the cases, at the same 
period of the disease, from the seventh to the ninth day, whatever 
be the treatment employed. This fact tends to lessen greatly the 
influence of remedies, not upon the termination (we put aside this 
view of the question) but upon the course of the disease. It proves 
also that pneumonia has a period of increase which it must fulfil, 
and that the different medications directed against it are perfectly 
powerless in arresting its ascending progress: — the proof of this is 
in the fact, that in cases where no treatment has been employed, 
an amelioration has not been the less manifest at this same period 
of the disease. Of this we have one remarkable example. 

The second part of the treatment now requires our attention, 
consisting of emollients, sedatives, and at times of tonics. The 
usual beverage was infusion of mallows sweetened with syrup of 
gum; in addition, usually, julaps containing from 3ij to gss of 
syrup of poppies. When the child was debilitated by a preceding 
disease, or when the constitution was feeble and delicate, there was 
added §ss of syrup of cinchona. 

Whenever any other disease, complicating the pneumonia, pre- 
sented any pressing indication, it was combated by the appropriate 
remedies. v.- 

The young patients were rarely submitted to an absolute diet. 1 
In those of the first category, whenever there was appetite, food 
was o-ranted. In the younger patients attacked with acute pneu- 
monia, the anorexia being usually complete, all aliment was with- 

1 The French diite is here and in all other places rendered literally, 
as meaning the deprivation of all nourishment of whatsoever species.— P. 


held for the first three or four days of the disease — but immediately 
on any appearance of appetite, the light soups, milk, and bouillon 
were prescribed. Young children support badly an absolute diet, 
and the disease is aggravated by many successive days' deprivation 
of nourishment. Older children were dieted, but as soon as any 
amelioration appeared, they were allowed bouillon and soup. 

It is very difficult to lay down general rules in therapeutics- 
nevertheless if it be allowed to us to point out a plan of treatment 
for the pneumonia of children, we would recommend the following: 

1. In a pneumonia supervening upon a chronic affection, and 
assuming itself the character of a chronic disease, no active medi- 
cation should be directed against it, but an attempt made to modify 
the general health. Particular attention should therefore be paid 
to hygienic precautions, avoiding the continued decubitus ot the 
child upon the back— prescribing the most absolute cleanliness, &c. 
As general treatment we would advise the use of light tonics inter- 
nally—and, above all, (the appetite still remaining in most cases,) 
we would prescribe fortifying and nutritive aliment, in a small com- 
pass. The diarrhoea is not to serve as counter-indication, for the 
diarrhoea of children by no means always depends upon an inflam- 
mation of the digestive tube : most generally it is dependent upon 
a softening of the mucous membrane, which has more analogy 
with anaemia than inflammation. As a tonic externally, the sul- 
phur bath might be prescribed, from which M. Jadelot thinks he 
has obtained some success. 

2. If the pneumonia be present as complicative of a pre-existing 
disease, we would not have recourse to the subtraction of blood of 
which we have already demonstrated the want of success— we should 
prefer the treatment by the tartar emetic, since in a certain number 
of cases recovery has followed its employment. We should not 
fear to carry this remedy to a very high dose proportionate to the 
intensity of the inflammation, and despite any slight contraindica- 
tions on the part of the intestinal canal. 

3. And finally, if the pneumonia were idiopathic, we would em- 
ploy the combination of bleeding and the tartar emetic we would 
however, not carry the loss of blood to any great extent always 
proportioning it to the gravity and extent of the inflammation 



We at first intended to append at the end of our work the greater 
part of the observations, which have served for its basis : but this 
project we have abandoned, as giving 1 to our little undertaking a 
volume too considerable. We have prefered to give only facts suf- 
ficient to prove the principal assertions we have thus far advanced. 
Thus, there will be found, in the following pages, examples of the 
different forms, which the pneumonia assumes, of the two periods 
observed in it, of the different alterations of the respiratory sound, 
of the numerous lesions of the pulmonary parenchyma, &c. &c. 
If we have not quoted an example of idiopathic pneumonia in 
children from five to fifteen years of age, it is because the periodical 
collections abound with cases of this nature, and we are desirous 
of pointing out only facts the least known. 

At the end of our observations, we have placed two tables of the 
pathological anatomy, representing the comparative frequence of 
the different forms of the pneumonia, as well as of the different 
other lesions of the lung, which most usually complicate the in- 
flammation of the parenchyma. 


Child set. three years. Constitution not strong. Acute pneumonia. Two 
well marked periods. Treatment by the tartar emetic. Effect upon the 
pulse and respiration. Amelioration of the local state on the seventh day. 
Final convalescence the twelfth. Disappearance of all rale the twenty- 
fifth day. 

Vaillant (Eliza) 8bt. three years, has been under treatment for 
more than a month in the ward St. Genevieve, for a diffused 
chronic eczema of the trunk. Ten days before entrance into the 
acute ward, she had commenced to cough, but her catarrh was so 
slight as not to oblige her to take to her bed. Oct. 12, she was 
suddenly attacked with fever and increase of cough. The 13th, 
she was brought to No. 2, ward St. Anne, where we saw her at 3 
P M., in the following state :— 

Constitution not strong : remains of the eczema on various parts 
of the body ; chest well formed. Decubitus dorsal, eyes closed, 
cheeks coloured, skin burning, pulse 160, full and regular Inspi- 
rations 64, without dilatation of the ala nasi: the child is re- 
markably somnolent. In front, on both sides, the respiration is 
17— a nl 5 


strong and pure. Behind pure, in the whole of the left side and 
the summit of the right ; but in the middle part of the right side it 
is obscure, and below, in two fingers' breadth, bronchial — the bron- 
chial character is especially marked in the slight cry that accom- 
panies the expiration. The resonance on percussion is diminished 
at the right base ; it is normal in the left. The cough is rare, with- 
out expectoration ; the tongue is quite moist, with a slightly white 1 
coat : abdomen distended and tympanitic : no stool since entrance. 
Prescription. — Sweetened infusion of mallows for drink. 

Take of Tilled 1 water, 3iv. 

Syrup of poppies, £iij. 
Tart. ant. and potass, gr. iij. 
Syrup, §j. 

This prescription, given by spoonfuls, determined no vomiting, 
but three or four loose dejections, and it was all taken on the 14th, 
at three P. M. Up to this time the febrile symptoms continued 
unabated; pulse 160, respiration 64. The hepatisation appears to 
have advanced. The percussion is flat in a greater extent than 
yesterday ; the respiration is obscure on the right in the two in- 
ferior thirds : in a strong inspiration, a bronchial respiration is 
heard in various scattered points of the inferior third. The skin 
is excessively hot. The prescription is continued, with an increase 
of the tartar emetic by one grain. The next day, (the 4th,) three 
quarters had been taken at noon without vomiting. The skin is 
less warm than yesterday; pulse 144, respiration 36. The child 
opens her eyes, commences to speak, and asks to sit up in bed; the 
tendency to somnolence has disappeared. This amelioration of the 
general symptoms, however, is unaccompanied by any propor- 
tionate change in the physical signs, as the respiration continues 
clearly and distinctly bronchial in the two lower thirds of the right 
lung, with flatness in the same space, and a subcrepitous rale at 
the summit. The same prescription is continued ; the tolerance is 
perfect, and the 16th the child's state is stationary. The 17th, the 
child has now taken in all fifteen grains of the tartar emetic, with- 
out any vomiting ; the pulse is 120, the respiration 36. The bron- 
chial respiration is present in the whole of the right lower lobe, 
and at intervals, after cough, there are heard some explosions of 
crepitous rale excessively fine. To-day the tartar emetic is omitted, 
being replaced by a julap of poppies. The 18th, at seven A. M. 
the child is in a peaceful slumber ; pulse 120, respiration 40, equal. 
The bronchial respiration ceases to be heard, except at the inferior 
angle of the scapula ; below this point, after cough, there exists the 
crepitous rale, excessively fine. 19th, pulse 126, respiration 28; 
same physical signs. 20th, pulse 116, respiration 28; the bron- 

1 Tilleul is the Tilia Europea: no corresponding preparation is found in 
the American Pharmacopoeia. Its real nature is unimportant, bein<* merely 
used as a pleasant vehicle. — P. 


chial respiration has entirely disappeared, together with the rale, 
only the respiration is accompanied by a sonorous rale posteriorly 
and interiorly on the right, and the percussion is a little less reso- 
nant than in the correspondent parts of the left lung. 

23d. All trace of the flatness has disappeared f pulse 104, but 
there exists posteriorly a somewhat abundant subcrepitous rale. 
This rale persisted until the 5th of November ; but the convales- 
cence may be considered as established on the 23d of October. 

Remarks.— This observation is a fine example of acute pneu- 
monia in a child of three years. With the exception of the expec- 
toration, there existed the greater part of the symptoms of the 
adult — acceleration of the pulse and respiration, "the stethoscopic 
signs, and flatness on percussion. The two periods which we 
have signalised in the pneumonia of children, from two to four 
years, are here well defined. Our young patient had coughed for 
ten days, but this slight apyretic catarrh did not prevent his run- 
ning about all the day in the wards; when suddenly and simulta- 
neously there supervened the acceleration of the pulse and the 
respiration, which marked the transition to the second period. 
Thirty hours after the commencement of the disease, the bronchial 
respiration had already manifested itself, but in a limited space. 
After this it was heard from the base to the summit of the lung, 
and followed the same course as in the adult. Jn this case, there- 
fore, we have, very probably, had to do with a pneumonia of the 
lobar form. The bronchial respiration offers the character common 
to that of children, viz. especially marked in the expiration. The 
tartar emetic appears here to have had a manifest influence upon 
the pulse and respiration. The fourth day, after the administration 
of six grains, the pulse was diminished by 16, and the respiration 
by 28. The sixth day, fifteen grains had been taken, and the pulse 
was still further diminished by 24 ; and, finally, on the seventh 
day we establish a manifest amelioration of the local state, and on 
the ninth the bronchial respiration had entirely disappeared. Our 
patient might be regarded as cured on the twelfth day of the dis- 
ease, although it was not till the twenty-fifth that the last traces of 
the rales had disappeared. 


Child of two years.— Generalised lobular pneumonia on the left, with a 
pleuritic effusion.— Simple lobular pneumonia on the right.— Two well- 
marked periods. — Duration of the catarrhal period one month. — Of the in- 
flammatory five days.— Access of suffocation, with the supposed appear- 
ance of the pleuritic effusion. 

Aliot, (Irma,) aet. two years, entered 24th November, 1824, the 
Hospital of Enfans Malados, and was placed No. 2, ward Saint 


The persons who brought her, stated her to have been sick three 
weeks, with anorexy, a slight diarrhoea, and cough. Submitted to 


our observation November 25th, we found the following : Consti- 
tution feeble, skin delicate, eyes black ; impetigo of the hairy scalp. 
The dentition is not complete, the canines of the lower jaw are still 
wanting; the child is always with her fingers in her mouth, as if 
suffering with her teeth; countenance natural; skin not hot; 
respiration 28, pulse 112. Percussion everywhere resonant. Be- 
hind and before there is heard a combination of the sonorous and 
large mucous rales ; the cough is rare ; the expectoration nothing. 
Tongue moist, abdomen a little distended, but indolent; no di- 

Until November 30th, the state of the child remained the same. 
Auscultation, practised every day, gave nothing but the same rales, 
and there were no symptoms of reaction. The 30th, in the morn- 
ing, the pulse was found accelerated as well as the respiration; 
pulse 160, vibrating ; 52 inspirations. Persistence of the same 
rales on both sides posteriorly, but more especially on the left. Per- 
cussion less resonant at the left than right base. 

December 1. Skin hot. pulse trembling, 180; respiration 60, un- 
equal, with dilatation of alee nasi. Posteriorly, in the two inferior 
thirds of the left lung, bronchial respiration, with percussion still 
less resonant than yesterday; on the right, persistence of the mu- 
cous rales, with diminution of the resonance, (julap of poppies, 3ij.) 

Dec. 2. Pulse 164, still small and trembling ; respiration 60, irre- 
gular. The respiratory murmur is not sensibly modified since 
yesterday ; however, the mucous and sonorous rales, heard in the 
right back, are replaced by a subcrepitous rale in the expiration: 
the inspiration is rude at the summit, (tartar emetic, gr. iv. ; dry 
cupping on the left side.) At four P. M. the child was found at- 
tacked with an access of suffocation, the face purple, the oppression 
extreme, and death appeared imminent. 

On the morning of the 3d, our young patient was, however, still 
alive ; pulse and inspirations as yesterday : countenance pale, skin 
of the body moderately warm, of the extremities cold. The bron- 
chial respiration has extended to nearly the whole of the left back. 
The flatness on percussion is complete; on the right, at the level of 
subspinal fossa, very distinct resonance of the cry, without any 
bronchial respiration ; inspiration rude, subcrepitous rale in the 
expiration, percussion resonant. The cough has ceased ; three 
quarters of the potion already taken have produced no vomiting, 
but two or three loose dejections. In the course of the day the con- 
dition of the patient continued to aggravate, and he succumbed the 
4th of December at midnight. 

Autopsy thirty-four hours after death-weather fine and dry. 

vib^es ema% *~ BOdy WeH f ° rmed; n ° cadave "c stiffness; no 
2&arf. -Calvaria strongly adherent to the dura mater- arach- 
noid smooth, transparent. Considerable quantity of Terosity m the 


subarachnoid tissue ; cerebral veins injected ; the brain, except a 
somewhat excessive quantity of the bloody points upon incision, is 
in the normal state. 

Neck. — Larynx and trachea healthy. 

Chest. — The right lung presents at the base some loose cellular 
adhesions. The left pleura contains a glassful of purulent serosity, 
and is covered with false membranes, soft, yellowish, and of about 
an eighth of a line in thickness. 

The right lung is supple, rose coloured in its greater part, but 
in its middle posterior third, (base of the superior, and summit of 
the inferior lobe,) it is violet coloured externally, and an incision 
reveals the presence of a considerable number of scattered points of 
a variable size, where the tissue of the lung is red, friable, and sink- 
ing when placed in water, (lobular pneumonia.) The rest of the 
lung is healthy, except the summit, which contains a tubercle the 
size of a small nut. The bronchi of this lung contain a spumous 
liquid, and are a little red, without, however, any alteration of 

Left lung. — The upper lobe is supple, rose coloured, containing 
neither tubercles, nor points of hepatisation ; the lower lobe violet 
coloured externally, marbled red and gray in an incision which is 
smooth, friable, granulated upon tearing, not floating upon the sur- 
face of water, either in separate pieces or in totality. This alteration 
occupies the whole lobe, and no single lobule remains unaffected 
in the midst of the general disease. The bronchi of this lobe are 
of rather a vivid red ; not dilated. 

The pericardium contains no serosity. The heart, carefully 
measured, is of normal dimensions; the auricles contain numerous 
yellowish coagula. 

The abdominal organs, examined with the minutest care, present 
no appreciable alteration, except a slight injection of ten or twelve 
of the patches of Payer, without softening. 

Remarks. — We find, also, in this observation our two periods of 
the disease well marked. After a catarrh of about a month's dura- 
tion, the symptoms of which we were enabled to appreciate, the 
disease commenced by a rapid acceleration of the pulse and respi- 
ration, and what is very remarkable, the percussion revealed to us 
the sio-ns of a pneumonia before the auscultation had thrown any 
light upon the affection. The access of suffocation, taking place 
thirty hours before death, appears to us to have coincided with the 
effusion. In probable proof of which, there is, on the one hand, 
the increase of the dulness, which, from being only relative, be- 
came complete ; and, on the other, the lung was not found flattened 
ao-ainst the spine, as if the pneumonia had been anterior to the 
pleuritic effusion. We must not forget, also, the resonance of the 
cry the subcrepitous rale, and the rudeness of the respiration, 
which put us upon the diagnosis of a lobular pneumonia of the 
rio-ht side, which was confirmed by the autopsy. And, finally, we 
remark, in the left lung a well characterised generalised lobular 


pneumonia, a tissue marbled with gray and red, the rapidity of the 
hepatisation having almost destroyed any isolated hepatised lobules; 
the lobules of disease which we met in the right lung are sufficient 
to justify this idea. 


Child of eighteen months. Lobular pneumonia slightly generalised, super- 
vening on a chronic enteritis. Absence of constitutional symptoms nearly 
complete. Death in the last degree of marasmus. At the autopsy, a 
generalised lobular pneumonia of the right, simple lobular of the left lung. 
Dilatation of the bronchi. 

Haering, ast. eighteen months, was brought to the hospital, Oc- 
tober 9, 1838. Born of healthy parents, she was put to nurse im- 
mediately, where she remained till the age of eleven months, when 
she was returned in perfect health. Two months before her en- 
trance at the hospital she was attacked with diarrhoea and vomiting. 
Admitted into the wards in the middle of September, she went out 
after a short stay, but returned in October for the same complaints. 

October 10, she was in the following state : — 

Eyes blue, hair blond, constitution feeble, dentition incomplete, 
the canines wanting. Countenance natural, sitting up in bed. The 
cheeks are cool and moist, the extremities cold and purple; 40 un- 
equal inspirations, pulse with difficulty counted. The respiration 
is perfectly pure, and the percussion resonant in front and behind ; 
the thirst extreme, the tongue moist; the surface of the abdomen 
purple, tense, resonant, indolent; abundant yellowish diarrhoea ;■ 
appetite still preserved. No cerebral symptoms. Until the 2d of 
November there appeared no change, except a constant and great 
emaciation. The diarrhoea is as abundant, and the respiration re- 
mains perfectly pure ; (the auscultation was daily.) 

November 2. In the right back the respiration is a little more 
feeble than in the corresponding parts on the other side ; here and 
there are heard some slight cracklings ; no symptoms of constitu- 
tional reaction. 

Nov. 5. On the right back, large, moist, and mucous rales at the 
summit; below, respiration obscure, and percussion a little less re- 
sonant at the base than on the opposite side. Pulse 140, skin 
slightly warm, no dilatation of a!a3 nasi; for the first time a 
slight cough. From the 5th to the 10th no change. 

Nov. 10. The cough is increased, the pulse insensible, respira- 
tion 52 ; at the right base, for the width of two fingers, bronchial 
respiration in the little dry expiration succeeding the inspiration; 
above, respiration strong ; on the left, expiration exaggerated ; the 
percussion is not resonant at the right base. 

Nov. 13. Pulse still insensible, respiration 32, without dila- 
tation of alas nasi; in the whole right back moist subcrepitous 
rale, resonance of the cry at the base ; on the left, sonorous rale ■ 



same state of the percussion. The face is yet paler than before ; 
the emaciation extreme ; abdomen and limbs are covered with 
ecchymoses, and the extremities oedematous ; diarrhoea still persists ; 
the cough is rare, and only when the child is made to sit up. 

Nov. 14. Pulse still insensible ; pulsations of heart distinct, 120 ; 
respirations 32 ; in front, the respiratory murmur is strong and 
pure ; on the right back subcrepitous rale very moist in the inspi- 
ration ; bronchial expiration ; dulness in the inferior quarter, in- 
creasing as we approach the base. 

Nov. 15. The skin is warm; pulse can be counted, 144, very 
small, respiration 36, without dilatation of alae nasi ; on the right 
back persistence of the same physical signs ; on the left, the sub- 
crepitous rale is heard throughout ; diarrhoea still colliquative ; 
paleness and emaciation extreme.

The treatment consisted of julaps of poppies, and a few grains of 
diascordiurn; 1 the pernitrate of iron (gutt. vi.) was exhibited for 
the diarrhoea; on the I lth, also, a blister was applied to the right 
back ; and the appetite being partly preserved, the child took milk 
and bouillon. 

Autopsy thirty-eight hours after death—weather cold and damp. 

Last degree of marasmus; numerous ecchymoses upon trunk 
and extremities. 

Arachnoid healthy, with considerable serous effusion under- 
neath ; pia mater not injected ; three or four spoonfuls of serosity 
in the ventricles ; brain normal. 

Larynx, trachea, and bronchi are but just tinged with red. 

The pleura, smooth and polished, contain neither false mem- 
brane nor serosity. 

Right lung.— AX the anterior part of the superior lobe there are 
seen some projecting, pulmonary lobules ; the vesicles are visible 
to the naked eye, and there are also visible some considerable bub- 
bles of air in the interlobular cellular tissue. At the summit, be- 
hind, a space, the size of a small egg, the parenchyma is red, 
friable, and does not float upon water; an incision gives issue to a 
yellowish purulent liquid, perfectly analogous to what is evolved 
m the bronchi, and which escapes from the little cavities formed 
bv their dilatation. The lower lobe is purple externally, upon in- 
cision it is a red colour marbled with gray ; is friable, and sinks in 
water- in many points there are small cavities anologous to those 
of the 'upper lobe; the scissors penetrate easily into the interior, on 
incising the bronchi, the mucous membrane of which appears con- 

, D iascordium is an electuary comprising a great quantity of ingredients 
of tonic, with some sedative properties. — P. 


tinuous with that uniting the above cavities; the bronchi of this 
lobe are of a vivid red, and contain a yellowish purulent liquid. 

Left lung. — Upper lobe perfectly healthy ; lower lobe is purple 
in its posterior and inferior third ; an incision reveals the existence 
of a considerable number of points, varying from the size of a pea 
to that of a filbert, red and friable, (lobular pneumonia;) the 
bronchi of this part are slightly reddened but not dilated, con- 
taining a moderate quantity of spumous liquid. The remainder of 
the lobe is healthy. 

The pericardium enclosed a spoonful of serosity ; the tissue of 
the heart is of good consistence ; the auricles contain some gela- 
tinous coagula. 

Abdomen. — The mucous membrane of the stomach is thin and 
softened in the great curvature. 

The mucous membrane of the small intestine is remarkably 
white, giving no strips, and its tenacity is extreme. 

The large intestine is of a vivid red in various points : its mu- 
cous membrane is softened in the red points, and offers a consider- 
able number of dilated, follicular orifices. 

The liver is pale, yellowish, and greases the knife; the spleen 
and kidneys are normal ; no tubercles any where. 

Remarks.— We find, in this observation, a type of that variety 
of pneumonia which assumes the aspect of chronic disease. As 
the pulmonary inflammation commenced under our eyes, we had 
the opportunity of following it in all its phases, and appreciating its 
duration. It is in a case like this, we have to felicitate ourselves 
for our daily and exact auscultation of all our young patients, with- 
out which precaution the half of our pneumonias would have 
escaped us. The symptoms of reaction were nearly inappreciable ; 
the acceleration of the respiration, however, and the results of the 
auscultation have clearly indicated the progressive increase of the 
disease. The extreme moisture of the subcrepitous rale had made 
us suspect a dilatation of the bronchi, and the autopsy confirmed 
our supposition.

Perrin (Clemence,) tet. four years, entered September 20 and 
was placed No. 11, ward St. Anne. ' U ' and 

This young patient, of delicate constitution, subject to diarrhrp, 
and eruptions upon the hairy scalp, entered for the first lj 
September: she was then convalescent of measles of thihti 
marks were still present. At this time we disTov-^ f ^ 
there existed a cough, the respiration to be pure and Une pe^ "^ 

ssi on 


resonant. She left the hospital the 14th, to enter again the 20th, 
attacked with a diarrhoea which had existed since her departure. 

Sept. 21, she was as follows :— Hair chestnut, eyes blue, face 
pale, emaciation advanced, constitution delicate ; countenance na- 
tural, hps pale, skin not hot ; pulse 96, respiration 32 ; percussion 
resonant before and behind; respiratory murmur perfectly pure ; 
pulsations of the heart regular, strong, distinct, and heard in the 
whole of both backs. A little cough, no expectoration, tongue 
moist, a little grayish; appetite still present; abdomen supple ; no 
oedema of extremities ; no cerebral symptoms. 

Oct. 5. The child complained of pains around the umbilicus, 
and some inequalities were felt in the abdomen at this spot. The 
following days the cough augmented, and there were heard some 
mucous cracklings, especially at the left base, which afterwards 
disappeared, leaving the respiration pure. The cough, however, 
persisted ; and, Oct. 7, there were heard some bubbles of mucous 
rale in the right back : but not only were there no symptioms of 
reaction, but the pulse was below the standard; pulse 64; the 
hands are cold ; the face extremely pale ; the extremities oedema- 
tous, and the diarrhoea persists. 

Nov. 3. Same general state. Percussion every where resonant ; 
the respiratory murmur is more rude at the right than the left side, 
but without rale. The pulse is nearly insensible ; still a little cough. 

From the 3d to the 6th November, the day of death, our patient 
continued in much the same state, with the diarrhoea still colliqua- 
tive : despite of which, however, the appetite was still preserved. 

Nov. 4. There are observed some aphthas upon the tongue and 
lips; the pulse continuing insensible, the respiration not accele- 
rated, the feebleness too great to allow the patient to sit up for aus- 
cultation, and she died Nov. 6, at seven P. M. 

Autopsy thirty-six hours after death — weather cold and dry. 

No cadaveric stiffness ; last degree of marasmus ; oedema of ex- 

Head. — Fontanella half ossified ; arachnoid smooth, transpa- 
rent ; no glands of Pacchioni ; considerable subarachnoid infiltra- 
tion of serosity ; the cerebral veins contain no blood ; the cerebral 
substance pale, of good consistence, containing three or four 
spoonfuls of serosity in the ventricles. 

Neck. — Larynx healthy ; trachea and bronchi contain a large 
quantity of purulent liquid, but their mucous membrane is healthy. 

Chest. — The pleurae are smooth, polished, and contain neither 
false membrane nor serosity. 

Right lung. — The middle, or small tongue-like portion of the 
lower and the lower part of the superior lobes, are purple exter- 
nally — penetrable by the finger, upon incision very finely granu- 
lated. Pressure causes to exude from the affected parts an infinity 
of small drops of a liquid like that in the bronchi, whitish, not 


spumous, and lodged in the little cavities formed by the dilatation 
of the bronchi, which is so great that their extremities are double 
in diameter the parent bronchus. The mucous membrane of the 
bronchi receives its coloration from the subjacent tissues. In the 
remaining lobes, which appear healthy externally, an incision re- 
veals a large number of indurated points, where the pulmonary 
tissue is red and friable, (lobular pneumonia.) Their volume va- 
ries from a filbert to the head of a large pin. Finally, in a large 
number of points, and especially along the anterior border, the pul- 
monary tissue is projecting, and presents a kind of thickening, 
where the pulmonary vesicles are clearly distinguished, greater in 
volume than in other parts of the lung. 

Left lung. — The tongue-like portion which is in front of the 
heart, and the part of the lung lying upon the diaphragm, in about 
an inch of the elevation, present an alteration of the parenchyma 
and bronchi similar to that of the right lung. At the summit of the 
inferior lobe there is a cavity capable of containing a large filbert, 
having its external wall formed by the pleura, and a communication 
with a single bronchus, whose mucous membrane appears to be 
continued into its interior. The liquid contained in this cavity is 
white, not spumous, analogous to that in the smaller bronchi. The 
remainder of the parenchyma is healthy, with the exception of 
some scattered points of lobular pneumonia. 

Neither the lungs nor the bronchial glands contain any trace of 

The pericardium encloses a spoonful of serosity ; the heart has 
its ordinary volume ; the valves are pale, with some coagula in the 

Stomach. — Mucous membrane rose coloured in the great curva- 
ture ; gives no strips at this part. 

Small intestine. — Mucous membrane pale, very thin, affording, 
however, strips of two or three lines. 

Large intestine. — In the last foot the mucous membrane is 
thickened, red, softened, &c. 

The mesenteric glands are tuberculous, and many of them 

The other abdominal organs present no appreciable alteration. 

No active remedies were employed against the pneumonia; the 
diarrhoea was merely combated by enemata of starch and poppies. 

Remarks. — Here is another very remarkable example of those 
pneumonias of a chronic form, which constitute our first variety. 
In this case the pneumonia was not generalised, and the symptoms 
of reaction were entirely wanting. As to the auscultation, it o-ave 
only negative results, in spile of the existence of the bronchial dila- 
tation. But the absence of many of the physical signs may easily 
be explained by the nature of the lesions found at the autopsy : 1. 
The absence of the bronchial respiration is very well explained by 
the slight extent of the pneumonia: if, however, the auscultation 
had been as constantly practised in front as behind, we should have 


probably detected it on the level of the middle lobe : 2. The ab- 
sence of rale, in the last days, is as easily conceivable, upon reflec- 
tion that the purulent fluid filling the bronchi was not penetrated 
by air. 

If the explanation of the absence of certain signs is easy, it is no 
less so to account for those in reality present. Thus, the roughness 
of the respiratory murmur in the right back is naturally explained 
by the existence of the numerous points of lobular pneumonia 
which the autopsy revealed. 


Child of three years. Lobular pneumonia appearing at the same time with 
an imperfectly marked measles, in the course of a chronic enteritis. 
Pneumonia becoming slowly general. Resolution still more slow. Last 
degree of emaciation. Death imminent. Amelioration six weeks after 
the commencement. Final recovery. No active treatment. 

Brerige, set. three years, was brought to the hospital September 12, 
and placed No. 9, ward St. Anne. Very little information as to her 
previous health ; but we learned that three weeks before, she was 
attacked with fever, cough, and an eruption of red spots over the 
whole body, (measles.) Since, she had suffered with diarrhoea and 
oedema of the extremities. 

Sept. 13th. Constitution frail and delicate ; hair blond, scanty; 
eyes blue, impetiginous scabs upon the lips ; upper and lower ex- 
tremities cold and purple, with a sensible cedema ; abdomen full, 
but no fluctuation; pulse regular, 112, inspirations 22; in both 
backs percussion resonant, and respiration perfectly pure ; same in 
front ; pulsations of the heart not loud, but distinct; tongue moist; 
diarrhoea abundant, like beaten eggs ; thirst great ; the child is 
very plaintive. 

From Sept. 13th to Nov. 8th, the diarrhoea remained the same; 
the emaciation advanced rapidly, but the oedema disappeared almost 
entirely. The respiration during all this time remained perfectly 
pure, and the percussion resonant. Auscultation had been practised 
every day. 

Nov. 8th. There supervened three or four vomitings, without 
any symptoms of reaction. 

9th. the skin is hot; pulse 160, respirations 44, without dilata- 
tion of the alse nasi ; slight cough for the first time since entrance; 
in the whole of right back subcrepitous rale, with inspiration and 
expiration ; on the left the respiration is strong and pure ; per- 
cussion every where resonant ; on the thighs, legs, and abdomen 
there exist little red irregular papules of the size of the head of a 
pin, disappearing under pressure ; no trace of eruption in the rest 
of the body ; diarrhoea still abundant. 

10th. The eruption has faded, having been confined to the lower 
half of the body. The pulse is imperceptible ; respirations 30 ; the 


warmth of the skin has disappeared ; in the right back subcrepitous 
rale ; in the left some rare crackles. 

11th. The eruption has disappeared ; pulse 130, respirations 36; 
same phenomena of auscultation. 

1 2th. No change. 

13th. Skin warm ; pulse 128, respirations 40 ; in the whole 
right back a subcrepitous rale heard at intervals ; no vesicular 
expansion at the base ; percussion less resonant relatively to the 
opposite side. 

14th. Skin warm ; pulse 156, respirations 48, elevating- the 
whole thorax, not anxious; slight dilatation of the alas nasi; in 
the whole right back subcrepitous rale, in the lower third with 
bronchial expiration ; percussion but slightly resonant at the right 
base ; respiration pure on the left side. 

Until November 25th, there appeared no change, except a con- 
tinued increase of the emaciation. The face is extremely pale, the 
diarrhoea persists, the symptoms of reaction have disappeared ; the 
same subcrepitous rale, dulness, and bronchial expiration in the 
right back — but the abundance of the rale frequently overpowers 
the bronchial sound. 

From Nov. 29 until Dec. 20, the child was examined every day, 
and each examination gave very nearly the same results, the sub- 
crepitous rale in the right back, dulness in percussion at the base, 
but without the bronchial expiration. The emaciation is at the 
last degree. 

Dec. 20. There exists a little amelioration ; our patient very 
cross and plaintive hitherto ; has become more pleasant ; she is 
seated in the bed; the countenance is a little better ; the pulse is 
116; the appetite has returned; the rale persists, but the dulness 
no longer exists. 

From Dec. 20 till Jan. 15, the amelioration continually pro- 
gressed. The appetite is good, despite the diarrhoea, the tongue 
moist, the emaciation commences to disappear and the strength to 
return. The rale, however, persisted until Feb. 5, when it entirely 
disappeared. The amelioration was not interrupted during the 
remainder of the stay at the hospital. 

No active treatment was directed against the pneumonia ; some 
slight astringents for the diarrhoea (syrup of ratanhia,) some ene- 
mata containing a small quantity of laudanum, as well as some 
julaps containing syrup of poppies 3iij, were likewise exhibited. 
For two days gr. xij. of the white oxide of antimony were added to 
the potion of gum. The diet was at no time rigid, as our patient 
preserved her appetite throughout the disease. 

Remarks. — This observation merits a very particular attention 
in consequence of the termination of the disease. The pneumonia 
appears under the most unfavourable circumstances at a time when 

the child was reduced to the last degree of emaciation and yet 

recovery followed. But for the final resolution of the pulmonary 
engorgement, how long were we obliged to wait ! The eruption 



occurring at the same time as the pneumonia, appeared to have 
more the characters of a simple erythema (erythema simplex) than 
of the measles. This opinion is confirmed by the fact that the pa- 
tient had already been attacked by the eruptive fever, which rarely 
appears twice in the same individual. The form of the pneumonia 
places it in our first species ; the concomitant eruption, whatever 
its character, appeared to impart to the disease symptoms of more 
than usual reaction ; an acceleration both of the pulse and respira- 
tion decidedly marked the commencement of the disease. The 
results of the auscultation deserve careful meditation, as this single 
history furnishes several examples of the different transformations 
of the respiratory murmur. 


Lobular pneumonia supervening in good health, in a child of two years, 
accompanied with cerebral symptoms. 

Sinet, (Pierre- Victor,) set. 2 years, No. 8, ward St. Thomas, 
entered Nov. 11, and died in the night of the 17th and 18th. 

This child, born at the full term in perfect health, has, however, 
never continued in the enjoyment of it. A few days after birth, he 
was attacked with a purulent ophthalmia, to which succeeded an 
impetigo of the hairy scalp, followed by frequently repeated colds. 
These°different affections so retarded his developement, that at pre- 
sent he walks with difficulty, speaks but a few words, and dentition 
has commenced only within five months, at which time he had 
slight convulsions and a diarrhoea lasting some days. 

Nov. 3, being in tolerable health, he was attacked with a violent 
cough attended with fever: on the morrow, during twenty-four 
hours, he had convulsions lasting from ten minutes to half an hour, 
and returning about every hour ; attacking the limbs, face, and 
eyes. The cough and fever have persisted since, and the child has 
remained pale, bloated, somnolent, without appetite or diarrhoea. 

Nov 12. Patient lying on back, face slightly coloured on the 
left side the ala3 nasi dilate considerably, the skin is slightly warm, 
the left foot is, however, a little colder than the right, and the con- 
trary is evident with regard to the hands. Pulse small, frequent, 

146 to 150. „ . . wr on . . 

The oppression is considerable. Respiration 76 to 80, irregular, 
sometimes less, sometimes more in number. The resonance on 
nercussion and the respiratory murmur are every where good. 
Lios dry, tongue moist, gums a little swelled and red, the incisors 
are hardly projecting. Abdomen somewhat large, full of gas, but 
supple and not painful ; no diarrhoea. (Infusion of mallows with 
honey, calomel gr. vi. emollient enema. Bouillon.) 

13 Fever and agitation all night— calomel has produced no de- 
iections (same prescription except the calomel.) 

14. Night as the former— cough a little hoarse and strong— no 


diarrhoea. The face is pale, lips dry and encrusted ; the patient is 
very irritable, crying whenever he is touched and hardly allowing 
an examination. 50 irregular inspirations, difficult, with a hard 
noisy and painful expiration. Impossible to count the pulse. Aus- 
cultation is almost impracticable, nevertheless, despite the cries, we 
thought we heard a mucous rale on the right side. (Same prescrip- 
tion, calomel gr. vi. laxative enemata.) 

15. Some agitation throughout the night, day somnolent, his 
sleep is tolerably tranquil, permitting us to count 30 irregular in- 
spirations and 114 small pulsations. As soon as he is awakened, 
he becomes immediately very irritable, and only a superficial ex- 
amination can be made. Our patient is bloated, with his eyes en- 
crusted, as also the nose and lips. Abdomen tense and pain- 
ful ; one dejection after the calomel ; a slight cough still continues. 
(Infusion of mallows with honey. Magnesia gr. 12. Emollient 
enema. Bouillon.) 

17. Slight stiffness of the upper extremities: the fingers are bent 
upon the hand and the hand upon the wrist ; they can be straight- 
ened but not without causing pain ; the feet are slightly flexed ; the 
sensibility is preserved but slightly diminished equally on both 
sides; pupils dilated but movable. The head is quite movable; 
these symptoms were not noticed by the attendants prior to the visit. 
The face presents sudden alternations of pallor and redness, the 
oppression is extreme ; the dilatation of the alae nasi considerable. 
There are still the accesses of irritability, even when not touched. 
Consciousness is still present, and drinks are swallowed with 
avidity. (Mallows, syrup of gum; magnesia, and calomel, aa. gr. 
iv. demi emollient enema. Bouillon.) 

During the day our patient had well marked convulsions in all 
the limbs for about half an hour. At the evening visit he is more 
tranquil. Pulse 148, respiration 58, unequal. The head is drawn 
backward, but without stiffness ; pupils less dilated ; the limbs are 
the same as in the morning ; sensibility the same ; skin hot with 
momentary perspirations. 

Our patient remained in this tranquil state, in full consciousness, 
and asking frequently for drink until the middle of the night, when 
he was again taken with convulsions lasting for a short time, and 
he died quietly about 5 o'clock. 

Autopsy thirty hours after death—weather mild and slightly moist. 

The body loaded with fat, presents a slight swelling of the ex- 
tremities, which have remained flexed as durino- Hf e . The thorax 
presents modosities at the union of the cartilages and ribs. 

Brain. — Cranium very voluminous and its walls are very thick 
in various points, and thin in others ; the anterior fontanelle is not 
ossified. Dura-mater very adherent to the bone but appears healthy. 
The arachnoid smooth, transparent, presents a few of Pacchioni's 
glands. In the pia mater there is an abundant serous infiltration 
without any granulations, or traces of inflammation. The simuses 


contain numerous coagula, some coloured, others discoloured : the 
central veins are slightly congested. 

The consistence of the cerebral substance is everywhere good. 
The cortical portion is slightly rose-coloured, the medullary is only 
slightly marked with bloody points upon incision. Ventricles con- 
tain three to four spoonfuls of transparent serositv; their walls are 
healthy. v y ' 

The spinal marrow presents no alteration in colour or consis- 
tence. There is only remarked rather an abundance of sub- 
arachnoid fluid, and an infiltration, more considerable than usual, 
between the bones and dura-mater. 

Thorax.— The right pleura has some recent adhesions, which 
are soft, gelatinous, and infiltrated with a yellow coloured serum. 
The lung of the same side does not collapse upon the opening of 
the chest. 

The whole of the superior lobe hepatised in the second and third 
degrees, is gorged with a great quantity of a sanious grayish 
liquid. At its external and middle portion there is a little cavity 
of the size of a filbert, filled with sanguinolent fluid, not communi- 
cating with the bronchi. 

The middle and lower lobes are hepatised in the second degree, 
nearly throughout, but especially behind and in the upper part : 
the tissue is dense red, smooth upon incision, granulated upon 
tearing, and easily penetrable by the finger. The anterior part o? 
the base alone remains unaffected and floats upon the surface of 
water. The healthy portions present some vesicles more volumi- 
nous than the others, apparently emphysematous. 

The small bronchi appear reddened from the colour of the sub- 
jacent tissues, and containing liquid mucus, not bloody. 

The left lung and pleura are perfectly healthy, and contain but 
very little liquid. 

The larynx and the large bronchi are healthy. 

There are no tubercles in any of the thoracic organs. 

The heart without any alteration, and of good consistence, con- 
tains numerous coagula in all its cavities. 

Abdomen. — The mucous membrane of the digestive tube pre- 
sents no notable alteration. Throughout its whole extent it fur- 
nishes strips of five and six lines, except at the great curvature of 
the stomach, where the strips are only two or three lines. The 
colour is a gray rose, and at intervals there is an injection, but 
limited in extent. 

The other abdominal organs are in the same heathy state. 

Remarks. — This observation is an example of pneumonia ac- 
companied with cerebral symptoms ; we observe at the first view. 
that the thoracic disease has not been entirely masked by the phe- 
nomena of cerebral reaction. The first symptom was cough, with 
an oppression, which was always considerable, and these two 
symptoms have persisted until death, although they diminished in 
intensity, and presented very considerable variations at different 



times. The auscultation was never properly practised; we are 
sure, however, that six days before the death the respiration ap- 
peared pure, and nevertheless we found the hepatisation advanced 
to the third degree. 

It is impossible to believe that so considerable a hepatisation, 
should not be revealed by auscultation if properly practised ; we 
must only think that there are pneumonias, which, by sympathy 
reacting upon the brain, give rise to cerebral symptoms, which, 
absorbing the attention of the observer, mask the symptoms of the 
thoracic affection. 

In the present case, the cerebral symptoms showed themselves at 
the beginning and end of the disease and are analogous to those 
described by M. Tonnelier, in a memoir in the Gazette Medicate. 
The author of this memoir asserts that this assemblage of cerebral 
symptoms exists in children, without any lesion of~the nervous 
centres, but of different thoracic or abdominal organs. 

Finally, to conclude, we must notice the form of the hepatisa- 
tion, which is lobar, and occupied only one lung, a fact in direct 
opposition with the opinion of Dr. Gerhard, who affirms, in chil- 
dren from two to five years, pneumonia to be always double and 
lobular in its form. This case, moreover, is not the only one, 
which contradicts the assertion of the American pathologist. 1 


Measles. Lobular pneumonia generalised in the second and third stages. 
Mucous rale. Masking for a long time the bronchial respiration. White 
softening of the mucous membrane of the large intestine. 

Delaforte (Theophila Alexandre), ast. two years and a half 
was brought to No. 2, ward St. Thomas, without any other infor- 
mation than that he had had the measles six weeks previously and 
had been sick ever since. 

Upon entrance Nov. 30, we saw him in the following state- 
complexion blond, skin fine and pale a little rough and scaly upon 
the extremities, giving the sensation of a dry heat, the face is ane- 
mic, infiltrated, colour of wax, the nasal line is very pronounced 
the eyes are encrusted, the lips dry, sticking together and pale! 
ihe alae nasi dilate considerably immediately preceding the in- 
spirations, the pulse is small and frequent, impossible to count 
lrom the patient's restlessness. 

On opening the mouth there are found only the incisors and one 
molar ; the gums are neither red, nor swollen, and do not appear 
pa.nfu 1; the tongue is moist and pale; the abdomen is large and 
soft, although filled with gas, without any tumour ; the live? how- 
ever projects a little below the ribs. Pressure especially upon the 
right side appears painful, augments the nasal line and causes a 
knitting of the eyebrows. Dejections frequent, loose and yellow. 

1 See the table of Pathological Anatomy. 


The cough is moist, not frequent ; the chest resounds moderately 
well in its whole extent; every where except in the left part and 
axilla, there is heard a large abundant mucous rale in both the ex- 
piration and inspiration, more abundant at the summit than the 
base of the lung. It is fine and subcrepitous in the front of right 
base, (white decoction, 1 julep with oxide of antimony 3ss. syrup of 
poppies gss. demi emollient enema: bouillon.) 

Dec. 1. At first sight our patient appears moribund, he is so pale, 
feeble, and nearly motionless. The symptoms, however, are the 
same as yesterday, except a slight forward movement of the lower 
jaw. The cough is less abundant, the rales still persist. (Same 

Dec. 2. Same general aspect. Our patient utters at moments a 
singular plaintive cry. Behind, the rale is the more abundant at 
the right base ; there is a bronchial expiration in the sub-spinal 
fossa and here the percussion is dull. Persistence of the diarrhoea 
— pulse small, frequent, cannot be counted — (oxide of antimony, 
3j.) Death in the evening of this day. 

Autopsy forty-four hours after death — weather cold and dry. 

Chest. — The pleurae present old adhesions posteriorly. 

Right lung. — Deep red externally, especially posteriorly ; volu- 
minous, not collapsing. Its superior lobe upon incision resembling 
the liver, is of a yellowish gray and red ; upon scraping it furnishes 
a sanguinolent, sanious liquid ; upon tearing, it appears granulated, 
and the finger penetrates without difficulty. This lobe sinks in 
totality to the bottom of water. 

The inferior lobe presents the same characters, with a redder 
colour, but only in the posterior portion. It floats only by the an- 
terior portion of its base, which however presents some points of 
hepatisation. The middle lobe, equally hard and large, presents 
some points of hepatisation, and floats in totality. The nodules of 
separate engorgement, small in number, vary in size from a pea to 
a filbert. 

The mucous membrane of the smaller bronchi transmits the 
colour of the subjacent tissues : where the bronchi are sufficiently 
large to furnish strips, there is neither thickening nor softening. 
They contain also a tolerable quantity of mucus. 

Lejt lung.— Externally marbled gray and red, but in general 
the colour is not deep— it floats in totality and in parts, except a 
very small portion of the base which is hepatised. It contains ra- 
ther an abundant quantity of a spumous liquid, and is a little less 
resistant than a healthy lung. 

The small bronchi of this lung are redder than those of the other, 
owing to the more vivid redness" of the subjacent tissues; the mu- 
cus is" also abundant. 

The bronchial glands are small and but slightly developed; 

* Principally mucilaginous.— TV. 
17__b ril 6 


there are no where any tubercles. The trachea and the large 
bronchi are of a grayish red and perfectly healthy. 

Abdomen. — Mucous membrane of stomach and small intestines 
of a normal colour and thickness, giving strips of from three to 
five lines. The patches of Peyer red and' somewhat developed are 
neither softened nor ulcerated. 

The large intestine is gravely affected : throughout its whole 
length, the. mucous membrane of a pale white is very thin and does 
not give strips in any of its parts. This intestine is filled with a 
yellow mucous substance, in large quantity. The mesenteric glands 
are small, numerous, not softened. 

The other abdominal organs are normal. 

Brain. — No alteration save a somewhat considerable subarach- 
noid infiltration. The ventricles contain four to five spoonfuls 
of serosity, without softening of the walls. The cortical substance 
is slightly rosy, and the medullary presents no bloody points. 

Remarks. — This is an observation of lobular pneumonia gene- 
ralised, agreeing entirely with our description of the passage of 
this pneumonia to the third degree. 

It shows that in young children, and in this kind of pneu- 
monia especially, the abundance of the rale may mark the patho- 
gnomonic signs of the pneumonia itself. 

The general state of the patient and the concomitant lesion of 
the large intestine permit us to rank this case in our first category; 
it must be, however, regretted that the previous history of our pa- 
tient was so incomplete, as well as the succession of symptoms 
from the commencement. 


General and capillary bronchitis. Mamelonated and partial pneumonia. 
Hepatisation and carnification, with dilatation of the bronchi. 

Fariol, (Jules,) aet. five years, entered ward St. John No. 6, De- 
cember 22, 1837, and died January 5, 183S. 

We have had but few details of the previous history of this 
patient, as his parents had him at home only a month before his 

At that time he coughed much, had a catching pain in the right 
side, but only at the moment of the cough : he was slightly bloated, 
had a violent fever, especially at evening, without any diarrhoea. 
Since that time, persistence of the fever and couo-h, which has re- 
curred in paroxysms, with blowing inspirations* followed by an 
abundant serous expectoration, and even vomiting. The pain in 
the side disappeared, to return again; the oppression was always 
considerable : the appetite was preserved, however, and there was 
no diarrhoea. 

Present state, (Dec. 23.) Eyes and hair brown ; skin white and 
delicate: face a little bloated, especially the upper lip, which is 


pale and encrusted; the nasal line is very pronounced ; the alae 
nasi are widely dilated a little before each inspiration. The skin 
is moist and warm ; pulse 136, rather small. The tongue is moist 
and clean ; the abdomen supple, a little tumid, not painful; two 
semi-liquid dejections since yesterday. Respiration difficult, but 
regular, 56; the cough manifests itself in paroxysms of hooping, 
lasting several minutes. In front, percussion gives a good resonance 
on both sides; on the right there is heard a very loud sonorous rale 
both in the inspiration and expiration. At the top of the lung, in 
addition, there is a prolonged expiration ; on the left, the' same 
sonorous rale exists during the inspiration only, while the expira- 
tion is very rough and hard, especially at the summit. Behind, 
the resonance is good and equal on the two sides: every where 
there is heard in the inspiration a mucous, mingled with a sibilant 
rale. In the two interscapular spaces, but especially in the left, 
there is heard a well-marked bronchial expiration. Very abundant 
sero-mucous expectoration. (Mallows, infusion, looch, with oxide 
of antimony 3j. ; syrup of cinchona §j. ; soup.) 

Dec. 24. General condition much the same ; pulse 140; respira- 
tion 60; skin of hands warm and moist, of the body dry and burn- 
ing. Behind, the physical signs remain the same. In front, the 
sonorous is replaced by a mucous rale on both sides. (Same pre- 
scription, oxide of antimony, 3ij., milk.) 

25th. Has had a slight sleep in spite of an abundant diarrhoea. 
Lips are now a little less swollen; the bloated appearance has 
diminished ; the dilatation of the alae nasi is less ; there are no 
facial lines, and almost no heat of the skin ; pulse 130, respiration 
50, nearly entirely abdominal. Physical signs nearly the same, 
except the mucous rale, which is, perhaps, less abundant, and at 
the middle of the right side it is more dry and crepitous. The 
expiration in the interscapular space is still heard. (Same pre- 

27th. Skin dry and warm; pulse only 120, soft, full, and regu- 
lar; the diarrhoea has ceased; same results from auscultation. 
(Same prescription ; oxide of antimony, 3iij.) 

28th. The swelling of the nose and lips has reappeared, with the 
bloating of the face, and the nasal line. The countenance is pale, 
indicating prostration ; skin hot and dry ; pulse 144, soft, tolerably 
large : respiration 44 ; tongue moist, rosy coloured, and trembling; 
abdomen, although supple, is tympanitic, and generally painful ; 
there is an abundant yellow diarrhoea The chest is sonorous ; the 
mucous rale, always very abundant, masks a little the bronchial 
expiration. Expectoration the same. (Same prescription ; oxide 
of antimony, gss. ; semi-enema of flaxseed and poppies.) 

29th. The general condition was considerably aggravated ; pulse 
146 small; respiration 56; abdomen continues painful, and the 
diarrhoea persists. The mucous rale is heard throughout the chest 
more abundant than ever; the bronchial expiration has disap- 


From this time the state of the patient continued to aggravate, 
with delirium constant up to the moment of death. From his ob- 
stinacy in scratching his nose it was covered with bloody scabs, 
and the cheeks became of a violet red. Death, however, did not 
arrive till the night of Jan. 4. During these six days, the collapse 
and feebleness prevented all careful auscultation : the mucous rale 
was always heard quite abundant ; and, in the latter days of life, 
there was added the tracheal. 

Autopsy thirty-six hours after death — weather cold and damp. 

The body is thin, without stiffness, and presents a slight putre- 
faction of the abdominal parietes. 

Thorax. — The mucous membrane of the trachea and large 
bronchi display fine points of a rather vivid redness, and even 
appear softened. The right pleura offers solid adhesions, with 
some false membranes, which are soft, vascular, and strown with 
little tubercular granulations. The lung is heavy, and marbled 
red and violet in separate lobules, and floats in totality ; upon inci- 
sion, a part of the lobules appear of a clear red, containing air and 
a sanguinolent serosity : others, of a deeper colour, are hepatised, 
breaking up under the pressure of the finger, and are surrounded by 
little collections of miliary tubercles. These collections are scat- 
tered through the three lobes, but in small quantities; the same 
lung contains also lobules of hepatisation, perfectly isolated one 
from the other, which sink in water, and yield, upon pressure, a 
sanious fluid not containing air. 

At the anterior portion of the middle lobe there is found a portion 
of tissue, the size of a nut, collapsed, flaccid, externally of a livid 
red, internally a little less deeply so; hard and resistant to the 
pressure of the finger, and sinking when thrown into water. The 
bronchi of this part preserve the same calibre from their arrival in 
this tissue until they reach the surface of the lung ; some even are 
a little dilated ; they contain an abundant puriform fluid, and their 
mucous membrane, after being washed, is too much softened to 
permit of the making of strips. 

The smaller bronchi of the other parts of the lung are not dilated, 
but are generally reddened, although the subjacent tissue is not 
uniformly so; they contain an abundant quantity of mucus filled 
with air. 

The left pleura offers some weak adhesions : the lung of this side 
presents externally clearly marked lobules of a violet colour, pro- 
jecting and solid under the finger: upon incision, these portions 
appear hepatised and congested, and there issues an abundant sero- 
spumous fluid, which is in some parts sanious, and contains air. 
The hepatised lobules, being well isolated, sink to the bottom of 
water, but considerable attention is necessary to obtain this result 
they are so enveloped by, and insensibly confounded with the 
simply engorged tissue. These lobules of hepatisation are nume- 


rous, and exist equally in the two lobes. At the anterior portion of 
the lower lobe there is found a portion of hepatisation the size of a 
filbert, presenting, upon incision, little cavities, the size of a lentil, 
communicating with each other by dilated bronchi, and filled with 
a puriform liquid ; they are lined by a smooth thin membrane, ap- 
parently continuous with that of the bronchi. 

The small bronchi of the other parts are like those of the oppo- 
site side. In this lunsr there are no tubercles. 

The bronchial glands, voluminous on both sides, are tuberculous 
on the right ; red," soft, and without tubercles in the left. 

All the cavities of the heart contain coagula, both coloured and 
the contrary, with a slight quantity of liquid serous blood. The 
border of the mitral valve is a little red and thickened; the heart's 
volume is not increased. 

Abdomen. — No abdominal organ presents any notable alteration : 
the mucous membrane of the intestines is every where of a good 
consistence, and furnishes strips of five and six lines. The colour 
is generally pale, except some arborescent deep redness scattered 
in a small extent over the large intestine. 

The liver, of the usual size, and containing the usual quantity of 
blood, offers a great number of gray demi-transparent granulations 
in the interior of its tissue and under the serous membrane. 

The spleen contains one crude tubercle of the size of a hemp 

Brain. — Arachnoid smooth, transparent, offering however a 
slight opacity about the glands of Pachioni, which are very nume- 
rous ; the ventricles contain but little fluid. The cerebral substance 
is every where of good consistence and colour. 

Remarks. — This observation is of great interest from the nature 
of the anatomical lesions, as well as from the results of the auscul- 
tation. We find united here examples — 1. Of matnelonated pneu- 
monia, that is, lobular pneumonia perfectly circumscribed, without 
any tendency to attack the neighbouring portions. 2. Of partial 
pneumonia, that is, of lobular pneumonia, with a tendency to the 
surrounding tissue. 3. Of limited carnification and hepatisation 
surrounding our two species of bronchial dilatation. 4. Of a gene- 
ral and capillary bronchitis, proved at the autopsy. All these 
lesions were consequent upon the hooping cough. 

As for the symptoms from the auscultation, we should remark 
that the separate nodules of hepatisation gave a bronchial expira- 
tion, which, at the end of the disease, was masked by the mucous 
rale,' the result of the constant accumulation of mucus, the conse- 
quence, without doubt, of the feebleness of the child. 



Vesicular bronchitis. Simple lobular pneumonia. Dilatation of the bronchi. 
Bronchial expiration masked by the mucous rale. 

Androif, (Edmund.) set. nine years, entered Dec. 19, 1837, died 
Jan. 2, 1838. 

This hoy, of a naturally good constitution and health, was at- 
tacked with measles about eight days before his arrival at the hos- 
pital, — the eruption having, by report, gone through all its periods; 
the fever and the cough continued, with epistaxis, diarrhoea, nau- 
sea, pain in the abdomen, and sore throat. 

Upon entrance, patient very well developed, not emaciated, is 
nevertheless considerably prostrated. The face, livid in spots, is 
covered with an abundant furfuraceous desquamation ; the alas 
nasi dilate a little, and the edges of the nostrils are surrounded with 
red scabs, in consequence of a slight epistaxis ; the lips are dry, not 
encrusted, and there is no facial line. The skin is slightly warm 
and dry ; pulse 114, large and soft; no cephalalgy ; the tongue is 
moist, loaded at the base, red at the tip, and there are some white 
patches upon the upper and lower gums. The patient complains 
of a slight pain in the region of the larynx ; the tonsils are a little 
red and swollen. The abdomen, generally painful, is a little less 
so at the umbilicus, and is soft, supple, without gurgling, rose 
spots, or eruption, but covered with some furfuraceous scabs. Last 
night there was a bilious vomiting, and numerous liquid dejec- 

The respiration is regular, 48 ; the cough moist, frequent, and 
still preserving the character peculiar to measles : the expectora- 
tion is sero-mucous : decubitus upon the back, but possible upon 
either side. The form of the chest, is good, without emaciation, or 
an excessive quantity of flesh. In front the resonance is good on 
both sides ; on the right there is heard a mucous rale occupying 
the whole side, more abundant, drier, and finer in the middle re- 
gion, ordinarily heard during both times of the respiration, but 
sometimes in the expiration only : on the left, the mucous rale is 
less abundant, and sometimes is entirely absent. Behind, the reso- 
nance is moderate, but equal in both sides ; in the right, subcre- 
pitous rale nearly to the summit, but more especially at the base: 
at the summit there is united with it a little prolonged expiration. 
The rale exists in the inspiration, and at times there is a sibilant 
rale in the expiration. On the left the respiration is strono- and 
rude, with an expiration at the summit, and a slight mucous rale in 
the whole height of the chest. 

(Mallows, syrup of gum, looch with kerrnes, gr. ij. ; semi-emol- 
lient enema, sinapisms, bouillon.) 

Dec. 21. The prostration and fever are greater; persistence of 
the vomiting and diarrhoea ; the chest is in the same state. (Same 
prescription ; kermes, gr. iv.) 


Decern. 22. Slight epistaxis ; the face is more purpled, and 
asphyxia appears imminent; the prostration is more considerable ; 
pulse still 144, but less full, respiration 50: tongue a little pointed, 
red at the tip, white at the base; profuse yellow diarrhoea : other 
symptoms the same. 

The auscultation gives nearly the same results as before, with 
only the following differences : Subcrepitous rale in the whole right 
back, but finer and drier in different points : there is a little expira- 
tion at the summit, where the rale is less : on the left, the rale is 
still less at the summit, where is a considerable bronchial expira- 
tion ; below there is an abundant mucous rale. (Same prescrip- 
tion ; kermes, gr. v.) 

Dec. 23. The colour of the face is more vivid ; the prostration 
is less, there has been a slight epistaxis ; the nose continues red, 
and covered with scabs : the lips are dry, the tongue white and 
moist, the abdomen is not painful ; only one dejection since yester- 
day ; has taken soup with a relish. Persistence of the febrile re- 
action and prostration. 

The auscultation continues the same in front, except that the 
mucous rale has become subcrepitous in nearly the whole extent, 
instead of merely in the middle portion. On both backs, abundant 
subcrepitous rale throughout, with strong bronchial respiration at 
the left summit, and a slight expiration at the right, in the same 
point. (Same prescription ; kermes, gr. vi.) 

Dec. 24. Agitation throughout night ; prostration this morning. 
The sore throat and diarrhoea have returned. Otherwise, persis- 
tence of the same symptoms ; desquamation of cuticle continues ; 
(same prescription, kermes gr. vii.) 

Dec. 25. Sleeplessness, agitation, and diarrhoea throughout 
night. The eyelids are red and encrusted, there is a slight nasal 
trait, and the alse nasi dilate considerably. The face is coloured, 
especially the left side. The lips are dry, tongue moist, and yellow 
at the base ; continual pain in the situation of the larynx, which 
does not however embarrass deglutition. The abdomen, slightly 
tense and tympanitic, is painful in the epigastrium and right iliac 
fossa. Pulse 120, regular, with heat and dryness of the skin. The 
oppression continues the same ; same cough, same expectoration. 

In the whole of both backs, there is heard a mucous rale, during 
both inspiration and expiration ; the bronchial expiration has dis- 
appeared. In front, same mucous rale, equally strong on both 
sides. (Mallows, syrup of gum, looch, kermes gr. viij. syrup of pop- 
pies, gss. semi-emollient enema, bouillon.) 

Dec. 27. Prostration extreme, heat of skin. Pulse small, 130. 
The cheeks are livid in spots, the nose is encrusted, bleeding, same 
physical signs, only the rSle is perhaps a little more fine and sub- 
crepitous on the right. The face presents two or three vesicles of 
varioloid, none on any other part of the body. (Same prescription, 
kermes gr. xi.) 

From this time till the day of death on the morning of the second 


of January, (five days after,) our patient's state was continually 
worse and worse, prostration extreme, hardly allowing the sitting 
position necessary for the auscultation, which gave always the 
same result, mucous or subcrepitous rale wherever possible to place 
the ear ; the skin was dry, except during the two or three latter 
days, when it was bathed in copious perspirations ; the counte- 
nance by degrees lost entirely its expression, the patient could with 
difficulty articulate; the pulse was augmented to 160, preserving 
the same smallness, and the inspirations to 60; the abdomen con- 
tinued painful, and there was an abundant, frothy, yellow diarrhcea. 
The same treatment was pursued in carrying the kermes as high 
as fifteen grains. 

Autopsy thirty-three hours after death — weather moist and warm. 

The body presents no stiffness, vibices, nor any trace of putre- 

Thorax. — The right pleura presents some redness and arbo- 
rescent vessels without any adhesions. 

The right lung heavy, but flaccid and crepitating, collapsing but 
little, red posteriorly, of a gray rose colour in front, is gorged with 
a quantity of sero-sanguinolent liquid, and penetrated with air. 
The incised surface, of a gray rose colour, presents the projection 
of the bronchi filled with mucus, together with a number of small 
yellow granulations projecting from the surface, about the size of 
millet seed and filled with the same mucus ; the tissue of the lung 
is more friable than normal, but it still floats upon the surface of 

The anterior portion of the middle lobe presents some engorged 
nodules, red, hepatised, easily torn and sinking in water; they are 
well isolated from the surrounding tissue, which is rose coloured 
and have a size from that of a lentil to a large pea. 

The small bronchi are red, filled with mucus, and are either aug- 
mented, or preserve the same size from their origin to the surface ; 
their mucous membrane does not appear softened ; they are also 
dilated in all the points where the granulations exist, that is to say, 
in nearly all their extent, especially posteriorly. 

The left pleura red, and containing some arborescent vessels, 
presents posteriorly some gelatinous, soft, and recent adhesions. 

The left lung is of a deeper red, swimming in its totality upon 
the surface of water, presenting red, projecting spots, scattered un- 
equally over its surface. The incision is marbled with a violet and 
a clearer shade of red ; the lobules are well defined, and separated 
by their colour and projection from the healthy tissue ; the deeper 
coloured ones, which are the more projecting, are granulated upon 
being torn, easily penetrated by the finger and sink" in water. The 
lower lobe presents the same disposition ; the hepatised points how- 
ever are smaller and more numerous ; one of them has suppurated 
with the formation of a small abscess, which does not however 



communicate with the bronchi. These latter are redder than on 
the other lung, but contain less liquid, and are not dilated. 

The large bronchi and the larynx, slightly red, contain a small 
quantity of liquid mucus penetrated by air. 

The bronchial glands are red, voluminous and softened. There 
are no tubercles any where. 

There is nothing remarkable in the heart or large vessels. 

Abdomen. — The stomach contains mucus and some of the 
kermes. The mucous membrane is of a vivid red, in large bands 
in the smaller curvature, elsewhere in small lines and points with 
occasional small ecchymoses ; its thickness appears great, espe- 
cially towards the cardiac orifice and the great curvature. Its con- 
sistence is variable in points close to each other ; the strips are 
sometimes from one to two lines, or from half an inch to an inch, 
indiscriminately in the parts which are reddened as in those which 
are not so, in the great curvature as in the smaller. 

The small intestines present no notable alteration ; the mucous 
membrane with a few arborescent vessels at the upper portion is 
gray and pale in the greater part of its extent, its thickness is good, 
and gives strips from three to five lines; in the duodenum the 
strips are only from two to three lines. 

At the lower portion there are some reticular patches, similar to 
a newly shaved beard, but neither tumid nor ulcerated. 

The large intestines are generally healthy, with a good colour 
and consistence of the mucous membrane ; the rectum, however, 
presents some vivid red spots, where the mucous membrane breaks 
under the forceps, giving strips of from two to three lines only. 

The mesenteric glands are slightly reddened, but not softened. 

The other abdominal organs perfectly normal, are all. however, 
except the spleen, gorged with a considerable quantity of blood. 

Brain. — Arachnoid, smooth and transparent nearly throughout, 
is a little dry, and presents along the grand fissure as well as at the 
vermiform process, a considerable quantity of the glands of Pa- 
chioni, surrounded with a slight opacity of the membrane. 

There is no sub-arachnoid infiltration, but all the small vessels 
of the pia mater are distended with blood, and there are even some 
small ecchymoses, which the scalpel moved over the surface does 
not push before it. 

The cerebral veins and the sinuses contain much blood. The 
cortical substance presents a little redness, and the medullary 
a considerable number of bloody points. The consistence is every 
where good, and the ventricles contain from one to two spoonfuls 
ofserosity. % 

This observation is important as proving the truth oi many ot 
our ideas already emitted. We find first a well marked simple 
lobular pneumonia, in a child more than six years of age ; we see 
besides an abscess of the lung, a vesicular pneumonia and dilata- 
tion of the bronchi. The first of these four lesions is so perfectly 
distinct from the others, that the symptoms appertaining to each 


may be perfectly appreciated. And finally we observe a com- 
mencement of pleurisy with simple lobular pneumonia. 

The whole of this disease has been developed after a measles, 
the desquamation of which we have been able to see. 

The lobular pneumonia was manifested by the characters which 
we have attributed to it. In the right front, a drier and finer rale, 
surrounded by one coarser and more moist, which finally entirely 
prevailed over the former ; on the left back, bronchial expiration at 
the summit, mucous or subcrepitous rale every where else, finishing 
by masking' the parenchymatous element, in proportion as the 
strength of our patient declined. 

We must now explain the existence of the same expiration at 
the summit of the right back, where the autopsy has not revealed 
the existence of a hepatisation ; first, however, we must remark 
that perhaps there really did exist one of those lobular pneumonias 
at the third degree, which so easily escape detection at the autopsy, 
the existence of which may be expected here from the physical 
signs. Unless this be the case, why this remarkable discordance 
between the lesions? The tissue, more penetrable than usual, 
floats nevertheless in water, and its colour is a gray rose ; if we had 
examined more closely, perhaps, we should have found the vesicular 
granulations surrounded by points of pneumonia at the third 

But even if this explanation be rejected, another may still be 
found in the dilatation of the bronchi : we know, in fact, from other 
observations, that this alteration may, in certain cases, produce the 
symptoms for which we are endeavouring to account. Finally, it 
must be noticed, that here, as in the other lung, the bronchial 
sound was marked by the mucous rales increasing with the accu- 
mulation of mucus in the bronchi. 

The symptoms of hepatisation were manifested in the upper part 
of the lung, and only during the time when the mucous rale was 
least abundant, a fact which proves that a mucous rale may mask 
the bronchial respiration, almost immediately, or from one day to 

We have spoken elsewhere of the result of treatment. 


Generalised lobular pneumonia at the first and second degree. Dilatation 
of the bronchi into small cavities. 

Fifrelin, (Joseph-Francois,) a3t. 2 years, entered at No. 8, of the 
ward St. Thomas, the 29th and died the 3lst of October. 

His father, (a German) speaks no French. Any history therefore 
of the previous health or of the commencement of the present dis- 
ease is entirely out of the question. 

Oct. 30. This child, of a dark complexion, and very little de- 
veloped, has so small a pulse as hardly to allow of its being counted. 


There is, however, no febrile reaction, and the patient is cold and 
pale. The alae nasi do not dilate, the respiration is oppressed, 40, 
unequal, with at times an appearance of stoppage and difficulty in 
the expiration, which is noisy and painful in the commencement. 
No cough. 

Resonance of the chest every where good except in the two lower 
thirds of the left back, where it is diminished. Here is heard a 
very fine crepitous rale, very abundant, without any bronchial 
character. Same in the axilla of this side. Right back coarse 
mucous rale not abundant, existence of the same in the two fronts. 

The lips are dry, encrusted and cracked; the tongue is moist 
and of a rose colour ; the nose is encrusted ; the abdomen is soft, 
flaccid, and does not appear painful ; diarrhoea very slight. 

Oct. 31. Our patient is moribund and will not permit an ex- 
amination ; no cough ; 58 to 60 inspirations ; same aspect as yes- 
terday. The crepitous rale of the left side is more abundant, and 
very well marked. Mucous rale on the opposite side ; diarrhoea 
slight ; death the same day, two hours after this examination. 

Autopsy twenty-eight hours after death— weather cold and damp. 

Left pleura healthy. 

Left lung, the lobules of which are very well marked, but the 
vesicles of which do not appear dilated, presents along its posterior 
border large and flattened bullae, formed by the pleura solely, and 
having the appearance of interlobular emphysema. Upon incision 
of these there exude small drops of grayish mucus, not containing 
air, puriform, and issuing from little round cavities, the size ot a 
lentil. These cavities communicate with the bronchi of which 
they are the continuation. Some exist at the surface of the lung 
and correspond to the bullae already mentioned ; others in the in- 
terior of the lobe are so closely situated as to form a species of cel- 
lular tissue being only separated in some cases by an imperfect 
partition : others are united by tubes of communication, apparently 
dilated bronchi, and which give off numerous branches, themselves 
dilated. All these are filled with the same fluid as the little cavi- 
ties. Their mucus membrane, not thickened, but coloured red by 
the subjacent tissues, is smooth, polished and continuous with that 
lining the cavities. At the extremity of one of the bronchi there 
exists a tubercle, situated apparently in the very interior of the 
bronchus. . 

The surrounding pulmonary tissue is easily torn, and is gene- 
rally red, some parts of it float upon the surface while others sink 
to the bottom, without any apparent difference of their physical 

qualities. . 

This description applies to the whole extent ot the lower lobe. 
The upper lobe presents some projections due to the interlobular 
emphysema ; there are none of the little cavities internally and the 
pulmonary tissue is slightly engorged. 


The mucous membrane of the larger bronchi, of a slightly vivid 
red, possesses a good consistence. 

The right pleura presents some rather finer and solid adhesions. 

The right lung, generally crepitating, but slightly reddened, pre- 
sents, in the middle of its inferior lobe, two nodules of hepatisation 
of the size of a filbert, in the middle of which are two cavities per- 
fectly similar to those of the opposite side. 

All the other small bronchi, not dilated, contain mucus perfectly 
penetrated by air. 

The subject was taken from us before we could possibly examine 
the other organs. 

Remarks. — Although this observation is doubly incomplete, 
from the want both of the anticedents of the history, and the re- 
mains of the autopsy, we cannot help inserting it from the import- 
ance of the details above mentioned. Besides every thing directly 
relating to the pneumonia is complete both in the pathological 
anatomy and auscultation. 

We see here a remarkable example of our two kinds of bronchial 
dilatation, and which appear to be seated either in the course, or in 
the extremities of these tubes. 

We can establish the difference between these cavities and the 
small pulmonary abscess. Around the bronchial dilatation there is 
found a lobular pneumonia on the point of becoming general, the 
hepafised portions being already united by an engorged tissue: the 
only difference between the portions of the left lower lobe lies in 
the circumstance that some of them float on the surface, while 
others sink to the bottom of water — in both c.ises there was the 
same colour, and the same friability: there existed here evidently a 
combination of points of pneumonia in the first and second degree. 
This opinion, moreover, is confirmed by the lobular pneumonia of 
the opposite lobe. 

The symptoms arc not less remarkable : we have, however, but 
a few words to say upon these, having already strongly insisted 
upon them in the course of the observation. This child," aged only 
two years, has presented a well-marked example of crepitous rale. 

The existence of this rale appears somewhat contrary to the 
lesions which we have found after death, but we find a ready ex- 
planation in the fact that the bronchial* mucus was not penetrated 
by air, and, therefore, could not give to the ear the sensation of 
bursting bubbles. In these circumstances the inflammation of the 
lung was manifested by physical signs, belonging to the degree of 
the disease. 




Lobular pneumonia after measles. Numerous abscesses of the lung. Double 


Lefevre, (Antoine,) oet. four years, entered Oct. 2, No. 35, ward 
S:. Jean. Mother healthy ; the father, within three months, has 
considerahly emaciated under a cough, haemoptysis, and night 
sweats. Nursed by his mother, this child was weaned at four and 
n half months ; has never had any cutaneous disease, nor swelling 
of the glands : first dentition was easy. Had the small-pox eigh- 
teen months, and the measles two months since : this last was fol- 
lowed by cough and expectoration ; has been in bed for fifteen 
days, and has much emaciated ; the appetite has been preserved, 
and there has never existed any complication of intestinal dis- 

Oct. 3. Hair blond, emaciation extreme, face pale and a little 
bloated, marked by the small-pox ; skin hot and moist ; pulse 120, 
small, with some softness : the tongue is clean, the abdomen simple, 
and not painful ; thirst, some appetite, slight diarrhoea ; oppression, 
slight dilatation of alas nasi ; 46 regular inspirations; cough slight, 
not abundant, loose ; expectoration sero-mucous. 

Behind, good resonance at the upper part of both chests, dimi- 
nishing sensibly at the lower part, but descending a little lower at 
the right than left. 

Behind, mucous rale in the whole of both lungs, existing in both 
times of the respiration — sometimes, however, in the expiration 
solely, intermingled with sibilant rale ; bronchial respiration, espe- 
cially in all the lower portion, and slightly in the interscapular 
space. On both sides, in front, resonance good and equal ; coarse 
mucous rale, mingled with the sibilant, in the whole front chest. 

(Mallows, syrup of gum, looch, oxide of antimony 3j., semi- 
emollient enema ; bouillon.) 

Oct. 4. Pulse 150, respiration 50 ; no diarrhoea. The physical 
signs vary only as follows : Right back, no bronchial respiration, 
except in the middle portion ; elsewhere, mucous rale more abundant 
at the base. In left front sibilant rale at the summit, mucous rale 
at the base : at the right summit respiration rude, with but little 
sibilant or mucous rale. (Same prescription : oxide of antimony, 

Oct. 5. Same state ; (oxide, 3ij.) 

Oct. 6. Sensible amelioration ; pulse 120, respiration 44 ; sub- 
crepitous rale small in quantity in both backs, a little more in the 
rio-ht ; resonance and percussion good, and equal on both sides. 

In front, a little mucous rale on both sides, especially at the base 
of the lungs. 

Three liquid dejections; no abdominal pains; appetite. Same 
condition during two days. (Oxide of antimony, 3j. ; soup.) 


Oct. 9. Prostration, diarrhoea, loss of appetite; pulse 150, small; 
respiration 48. 

Right back, dulness on percussion in middle portion, with cre- 
pitous rale and bronchial respiration. Below, and to the outside, mu- 
cous and unequal crackling ; at the summit, some mucous bubbles 
at intervals. 

On the left side, less resonance on percussion at the base, ex- 
tending round to the side. Rather large mucous rale, with a slight 
expiration at intervals. 

This falling off, however, was not followed by any long-continued 
reaction. (White decoction, syrup of poppies, §ss.) 

Oct. 12. Fever slight; pulse 96, respiration 34; tongue clean, 
diarrhoea less : the amelioration in the local symptoms, however, 
not great. 

In the right back the resonance is returned in a slight degree, 
but there is still a persistence of the crepitous rale and the bron- 
chial respiration : at the top of the same side there exists a slight 
prolonged expiration, with a rather abundant mucous rale after 

On the left, at the summit, the respiration is strong : at the base 
it is obscure, without rale ; dulness on percussion the same. In 
front, respiration pure. (Oxide of antimony, 3iss.) 

Oct. 18. The disease has continued stationary up to this time : 
the diarrhoea is a little less, but the cough is increased ; paleness 
and prostration : the flies commence to gather about the nose, eyes, 
and mouth ; skin hot ; pulse 150, with an intermitting stroke ; 
respiration 56; oppressed, thirst excessive. 

Continuance of the dulness on left back, from the angle of sca- 
pula downwards, with subcrepitous rale and bronchial respiration, 
under and to the outside of the angle of the scapula: at the summit, 
mucous rale at intervals. 

On the right side, same state as before. In front, respiration pure 
on both sides. 

Same prescription. 

Oct. 19. Notable aggravation of local symptoms. On the left, the 
flatness extends to the top of interscapular region. In the whole 
extent of this there is bronchial respiration and subcrepitous rale : 
at the base the rale is drier and more crepitous : at the base of right 
back little resonance upon percussion, with subcrepitous rale and 
bronchial respiration. At the summit, mucous rale, both in the in- 
spiration and expiration, disappearing after cough, whilst, on the 
contrary, all the other rales are augmented by it. In front verv 
abundant mucous rale throughout the right side, especially under 
the clavicle. (Oxide of antimony, 3ij.) 

Oct. 20. Severe pain under right nipple; and there are heard at 
this point explosions of a subcrepitous rale during both the inspira- 
tion and expiration. Further than this, same local conditions as 
yesterday ; skin warm ; prostration more considerable. 

Oct. 21. The pain of the side has diminished. Behind the dul- 


ness continues, but there appears more respiratory sound, unless it 
may be that we hear a very distant bronchial respiration. At the 
summit some mucous bubbles. 

Oct. 22. Oppression extreme, respiration 66, dilatation of ala? 
nasi considerable ; pulse 150, small, hurried, a little irregular ; 
thirst excessive. 

The left side appears still a little painful. On this side, behind, 
under the axilla, and even in front, the dulness on percussion is 
considerable. The respiration is inaudible in the whole lower part; 
heard only at the summit behind, and there it is bronchial : persist- 
ence of the same symptoms in the right side. 

Oct. 23. Death at 8, A. M. 

Autopsy thirty-two hours after death — weather cold and moist. 

Emaciation extreme, with flaccidity of the flesh ; no stiffness, no 
vibices ; putrefaction somewhat advanced upon the abdomen. 

Chest. — The left pleura — rilled with an immense quantity of 
a serous liquid, containing floating flocculent albumen, lined in 
some parts with soft and not thick false membranes — is in itself red 
and injected. The left lung, compressed upon the vertebral column, 
is red and solid, and sinks immediately in water. On incision it is 
smooth and red, and presents the projecting orifices of a number of 
bronchi. The texture, granular when torn, is easily penetrable 
by the finger, but rather less so than in the usual hepatisation, due, 
without doubt, to the compression by the effused liquid. 

In its interior are discovered a great quantity of small cavities, 
varying in size from that of a hemp-seed to a large pea, and filled 
with pus, mixed with coagula of blood. Some of these cavities 
communicate with the bronchi, the opening of which are easily 
distinguishable. At the point where the bronchus opens into the 
cavity, the mucous membrane appears cut short off, and presents a 
visible solution of continuity, which may, in some instances, be de- 
monstrated by the formation of strips. These bronchi, slightly 
reddened in fine points, and containing a little spumous mucus, do 
not appear dilated : a considerable number of these cavities do not 
communicate with the bronchi, but appear rather surrounded by 
them. These abscesses, so numerous that no attempt was made to 
count them, do not communicate one with another. 

No tubercle any where in this lung. 

The ritrht pleura presents the same alterations as the left, except 
that it contains only a few spoonfuls of serosity. 

The right lung, not solid like the left, floats in totality upon the 
surface of water. The finger, passed over its surface, detects small 
hard bodies, which answer to engorged portions of a deep red, of 
the same size and form as the abscesses of the opposite side. These 
portions are solid, and easily broken down under the finger : they 
sink also to the bottom of water, provided they be properly isolated 
from the surrounding tissues. Some of these points of pneumonia 


are traversed by bronchi, which do not change their natural aspect. 
The bronchi generally exhibit a small number of red points in 
their mucous membrane, and are filled with a spumous mucus. 

The surrounding tissue, red upon incision, abundantly gorged 
with blood and a spumous serosity, floats upon the surface of water, 
and does not break under the pressure of the finger. 

A small part of the base of the inferior lobe is reddened, filled 
with a sanious fluid, breaks down under the finger, and sinks to 
the bottom of water ; the remainder of this lobe, containing no 
hepatised portions, is merely much engorged. 

No tubercles. 

The bronchial glands, large, red, and softened, are not in the 
least tuberculous. 

The heart, filled with coagula, some coloured and others the 
contrary, presents nothing but a hard and thickened adhesion of 
the aortic valves, which prevents their application against the 

Abdomen. — The mucous membrane of the stomach, containing 
a few arborescent vessels, is, however, normal in its thickness, and 
affords strips of several lines. 

The mucous membrane of the small intestines, of a gray rose 
colour, is healthy, and presents at its inferior porlion some nume- 
rous reticulated patches, slightly thickened, but not softened. 

The mucous membrane of the colon generally of a rosy red, 
slightly thickened, furnishes no strips. 

The liver of a normal size is generally red, hut the two sub- 
stances are distinct. 

The kidneys contain much blood, but are healthy. The bladder 
contains urine which is troubled and deposits a sediment. 

The pancreas are red and gorged with blood. 

The spleen, not congested is of its usual size. 

The peritoneum is of a rose colour, the subperitoneal vessels are 
gorged with blood ; in a word, all the abdominal organs except the 
spleen contain a considerable quantity of liquid black blood. 

Brain. — The dura mater, very thick, is adherent at the anterior 
fontanelle which is ossified. The arachnoid slightly opaque along 
the longitudinal fissure, presents a large number of Pachioni's 
glands, disposed in groups : there are some of these also along the 
superior vermiform process. The cerebral veins are distended 
with blood and the superior longitudinal sinus contains a firm 
coagulum. The pia mater is infiltrated with a moderate quantity 
of serosity. The ventricles not dilated contain very little serum. 
The cerebral substance is generally soft. The fornix is sensibly 
softened as also the tubercular quadrigemina upon their surface 
and the anterior peduncles. All these softened parts are white! 
The medullary substance presents but few red points, the corticai 
is generally rose coloured. 

In no organ were there found any tubercles. 

Remarks.— The first impression from the reading of this obser- 



vation, is that our patient was attacked with a general tuberculisa- 
tion ; for it is precisely in similar circumstances that this lesion is 
found in children. We have already spoken of the diagnosis in a 
case of this kind. But instead of tubercles, we find a lesion much 
more remarkable for its rarity : viz. abscess of the lung. We have 
already spoken sufficiently of this termination of lobular pneumonia 
not to be obliged to return to it. 

In this case the lobular pneumonia of the right side was mani- 
fested by the bronchial expiration at the summit of the lung, and 
this symptom was finally masked by the mucous rtle. The alter- 
nations of abundance and rarity presented by this rale, explain the 
irregularity of the other physical signs ; we must, however, admit 
the existence at one time of a more extensive pneumonia of the 
right side terminating in resolution ; the bronchial respiration and 
the dulness upon percussion recognised at the commencement, the 
engorged state of the lung at the autopsy after the disappearance of 
these physical signs are proof of this. Finally, in this same right 
side there was developed a grave pleurisy, although there had only 
existed in this lung a lobular pneumonia.

Several very interesting consequences may be deduced from 
these tables : 

1. Vesicular bronchitis does not exist in the simple state. 

2. The lobular pneumonias free from all complication are very 


3. From eighteen months to five years the most frequent pneu- 
monias are the simple and generalised lobular ones. 

4. Under this form the pneumonia is always double; conse- 
quently it is the form of the disease rather than the age of the 
patient, which makes it double or simple. In proof of this, the 
lobular pneumonias which are far from rare between two and five 
years, ordinarily occupy only a single lung. 

5. After the age of five years the lobular pneumonias are rare. 

6. In the idiopathic pneumonias, the right lung is the most usu- 
ally inflamed : it is not the same in pneumonias complicating other 

7. The lobar hepatisations are more frequent in the lower lobes. 

8. Carnification is a frequent lesion : we have never met with 
it after seven years. It exists rarely uncomplicated. 

9. Bronchial dilatation is seldom met with after the age of five 
years. Very rare in the uncombined state. And is found indif- 
ferently in all parts of the lung.
